When trying to generate an aggregation report on the root node of a preflop small save, I'm getting an error message saying "index was outside the bounds of the array". Any idea what the problem is?

How can I create a subtree from a preflop solution to investigate different flops (that weren't in the original preflop solution). When I do "Create subtree configuration" I get "This feature only works if there is a known basic configuration of the tree."

Edit: I should note I'm using one of the PioCloud samples (.cfr file). Do I have to have the actual file used to create the original tree for this to work? It seems like the solver should be able to just take the ranges, pot size, stacks and available lines from a given node and create a tree from it.

okay,

I solved a flop spot, and was wondering about other flops.

I was thinking that the aggregation report would give me the excel spreadsheet for various flops, which I could then compare EV and EQR with.

So I thought i needed to run an aggregation report across multiple files which I needed to generate first with a script.

I started a script , with your help, and it did the full 180+ flops. The black box finishes and says you can close the box, and find the report in whatever file.

I think the next thing to do is to run an aggregation report on multiple files?

I press the multiple file aggregation report button

In one box on left it says:

the next box is empty excpet for a message about not finding ranges.

So I assume I am in the wrong spot?


Can you please tell me if what I am doing is the right idea? If so, after running the 184 flop subset (which may not be saved correctly, but I do find the whole group in Saves.) can I actually compare the flops?

thanks

Hi there!
Is it posible to use an SSD M.2 disk instead of RAM memory as virtual memory for Pio Solver trees? If so... How? Is it possible to use both? Which difference will be?
Because is so much cheaper...
Thank u!

So piosolver tends to prefer checking back say QQ for example on a 34K 2tone flop at a higher frequency when we don't have a bdfd than it does when we do hold a bdfd. Ik piosolver doesn't take into account the value of protection so I'm wondering how this should be applied in practice? Should we always do as pio says (assuming we're playing against close-to-optimal opponents), or should we 'take it with a grain of salt'? I've went from prefering to x back with bdfd to checking back more often without bdfd but I'm starting to consider the possibility that this may be -ev? what are your thoughts?

Is there any way to compress full saved trees to reduce the space they are taken in disc?

ran the steps as suggested on pg 26. (thanks Roachru for a great tutorial)

it stopped at 45 out of 237 with an error message:

Key could not be found in dictionary

So i attempted a smaller script

14 random flops or so

everything seems to be working well, I run the script, finish, open the file, get to the root, then go to run multiple aggregation report

it shows a screen, which I ok, and then it again gives me same error at same exact spot 45/237?

did i screw up again?

It looks like you have more than one script file in the folder and PioViewer is unable to determine which script contains the config you want. Create separate empty folders for trees with a given config (the script will be automatically saved there as well) and the problem is going to disappear.
It's not much a problem either, only the config loaded to the graphical interface is different, the trees themselves are ok as you have notice.

Trees with many sizes are humongous. Using 3-4 sizes at most spots is already more than we thought is reasaonable. The solver handles those trees somehow but it take a long time. That is expected.

You can follow the process you described for specific turn and river and that is in fact quite a good idea. There is a feature which lets you cut a config at a chosen place and create a new subtree to make the task easier. The feature is described here:

https://www.youtube.com/watch?v=1PEmsGaGLvk (point 2)

Yes, especially with the prefllop solver which sacrifices a lot of accuracy to use less memory. You shouldn't expect to get accuracy much better than 2bb/100 for those trees (most of the exploitability is postflop anyway because of reduced accuracy) although the solver is often able to go to 1bb/100 or even less.
Please try downloading the newest version of the viewer (and substituting it in your Pio folder). It should be fixed there:

https://www.dropbox.com/s/6p13pzi7j3...iewer.exe?dl=0

Running aggregation report in the root in the preflop tree doesnt make much sense though (there isn't anything to aggregate) so maybe some other features to show EVs/EQs/Strategies would be more suitable there.


That's on the list of things to fix. For now you have to copy the ranges manually (preferably copy them to the range selector and save) and then create a new flop tree yourself using those ranges as starting ones.

It looks like you have a lot of random files and scripts in the folder. This won't work as the viewer has no to know which trees and are included and what config was used to create them. Create fresh empty folders for every script and save in it. It will work then if you follow the steps in the FAQ video (load one of the tree, choose a line to run the aggregation report with, etc.)

It's way cheaper but also like 2 orders of magnitude slower. It wouldn't work.
You can try it by ignoring memory check (search for ignore_mem_check in this thread on last 2-3 pages, I can't link right now) but it's highly recommended not to do that

Pio takes into account protection and everything else (they directly manifest themselves in EV of play which is used to adjust strategies). Pio doesn't treat streets separately, it always goes down the whole tree so all the nuances on turn/river play have influence on he flop strategy. If Pio doesn't like betting a certain combo there is a reason for it although that reason may be hard to discover or intuitively make sense of from the human perspective.

We have small and micro saves for that. There is no way to make full saves smaller at the moment.

It again seems like you have a mix of various configs, scripts and saves from different configs in the same folder and the aggregation building tool is confused. There should be only 2 things in the folder:

-the script used to create saves (.txt file)
-the saves themselves (the .cfr files)

I am sorry for delays and a bit hastily written answers. I don't have access to my main machine right now. Everything is going to be back to normal tomorrow. I appreciate everyone's patience

Is there (or will there be) a text interface command to create a subtree?

It's a lot of work to programatically recurse through the full tree and then map the branches to new lines in the subtree (since the bet amounts change depending on what node becomes the new root).

I found some surprising behavior: create subtree with a turn card selected uses ranges before the card was dealt, meaning there are impossible hands that contain the turn card in a player's range on the parameters tab. This is resolved when you actually select "build tree", but I think the parameters should prepopulate with the ranges at the selected subtree node (in this case it is a split node) so that there isn't an apparent contradiction. Is there a reason it does it this way?

Probably not, at least not in the near future.

There will be "show_all_lines" command which will make it easier (no need to recurse).

No reason, we didn't think it's important. The solver discards the hands which are dead anyway and you may want to change the turn card later to try another runout. We just didn't think it's important to be honest.

Awesome, "show_all_lines" sounds great!

Is there any way to have the save path for a script be relative to the script? Using a relative path ends up relative to the solver exe, and calling the solver with a different working directory errors out ("pftables.dat is missing"). The error seems totally reasonable, but it would be cool if relative paths in scripts were relative to the script file, at least optionally.

We use standard libraries for opening files so you would need to find a way to do that in Windows. Most programming languages have a way to open a process and set "cwd" (current working directory). Anyway, the simplest way is to just copy pftables.dat file to the place you have your current working directory set to so the solver can find it there

I am a bit confused by the all-in option. I have deselected it and set a 200% pot limit yet PIO overshoves on the river. Am I missing something? screenshots of the setup and the R spot below

Ah right, I get it. Just happy that there is an explanation. I kept deleting my trees and re-running thinking I messed up till I eventually realised that the tree itself was fine but parameters were incorrect. Pretty frustrating but we will live and learn. Ty sir.

Would be nice to have a feature inside script generation to generate random flops under certain constraints. For example being able to generate random flops with cards under T. Or to generate flops with two broadways and a rag. It would be very useful when you want to create specific scenarios

hey, can I somewhere buy "solved" hands by PIo? ty

Your screenshots don't work. I recommend sending us a config (you can do it by clicking big "copy to clipboard" button and then copying it to pastebin.com and linking here).

There are good reasons for the design where configs and the saves themselves are separated. The viewer needs to find the config. Usually when you make a simple save the config file is saved along with it. In case of scripts the viewer looks for the config in the script file. That's why there should be a separate folder for very script and saves resulting from it.
Another advantage is that if you are forced to terminate a script for whatever reason you can re-run it later and it will skip over already done trees (as long as they are still in the original folder).

While this is not possible at the moment you can paste any flop subset into scrpt generation window. This means that if you have a programmer friend they should be able to write a simple generator for you.

We don't provide such service ourselves but our friend runs PioCloud service, here:
http://piocloud.******.com/

Feel free to ask on our Skype group as well. Some people have a lot of postflop saves laying around

I like the option to copy a strategy to excel, but is there a way to for multiple flops at the same time? Like, if I run a script and I want to do some analysis of the strategies across multiple boards in excel, is there a way to do this without going into each file and copying it manually? Maybe it's something I can put in the script so it automatically does this for every board it solve

Another very similar question. Is it possible to copy the strategy to excel for every point in the game tree at once?

If both them answers are yes is it possible to do them both at the same time.

Occasionally when I do aggregation analysis, I get an error :

ERROR: load_tree couldn't open
(Path), the file doesn't exists or isn't a valid save

In fact the file does exist, and I can open it just fine. Any idea what's causing this? If you have no idea I can send the files.

You can run a multiple file aggregation report:
https://www.youtube.com/watch?v=5Ozjfnatwms (question number 5)

but that will show you strategies/evs/eqs in one chosen spot (although an all flops separately as well as aggregated ones).

It isn't. A typical flop tree has hundred of thousands and often millions decision points. That Excel file would be way bigger than full saves which are already humongous.

Things to check:

1)are you running the newest version of the viewer (1.9.2.5)?
If not you can get it from here:
https://www.dropbox.com/s/6p13pzi7j3...iewer.exe?dl=0

2)Do you have any strange characters in the path (anything not in a Latin alphabet may cause problems as well as very long paths and names)

One thing to try is to copy the saves to some simple folder like C:\MyPioTest and attempting to run the report there.

I get you can't use pio solver while playing. But can you play while a script is running and pio solver is closed?

I'm running 1.9.2.0, but the problem has occurred before as well so doubt that's issue. I changed the path but still same problem.
