just a basic/stupid question
If we have infinite computing power, piosolver would still only be able to solve a scenario to 0.0001% exploitability or whatever because its about what algorithms were given/how it was programmed? how can the nash distance be evaluated or is it just estimated?
Can anyone suggest a link about how solvers are constructed?

There are some artificial limitations in the algorithm now which causes it not to converge to exactly 0. Those are in place to make some other cases faster. I think it converges to almost 0 anyway for all cases but I can't be sure. Sometimes it takes a long time.
In principle the only limitation is a numerical one (fractions aren't represented exactly by computers and thus we can't hope to have exact solution) but this is extremely minor factor.
When we are back to work on the algorithms this will improve a lot although as it is now it's not a priority (the priority is to get to low exploitability fast, not to squeeze every last fraction of % near 0).

We calculate it exactly (as far as numerical representation allows). It's very easy to do:

1)Calculate EV of current approximation by walking the whole tree, evaluating every branch and summing it up in the root
2)Do the same for maximum exploitive strategies

See what the difference is, to be more specific, see how much would perfect adversary (one playing maximum exploitive strategy) win against current approximation per hand. That number is "exploitability" we display.

Those are computationally easy and fast operations so we are able to give them while solving in reasonably short intervals.

It's a problem because this is a relatively new thing and people who are ahead of the pack (for example us) aren't very likely to give information for free.
If you have solid math background I would recommend this website: http://jeskola.net/cfr/ and anything you can find by this guy. He is one of the few who both understand how to write fast solvers and shares some information publicly.

Has anyone had any success trying to run this w/ Wine on a mac?

People run it using Parallels or Bootcamp on Mac. Wine will be problematic. I tried some time ago and the viewer looked awful but I've heard they improved Net Framework compatibility a lot in latest releases so maybe it's worth a try.

Hi,

PioSOLVER-free was updated today: http://piosolver.com/collections/fro...piosolver-free

Main additional things are features in Range Explorer like:
-equity realization
-preflop equity

It contains all the features from commercial versions other than flop solving. You can read more here:
-http://piosolver.com/blogs/news/33960772-performance-improvements-new-viewer-features-and-a-bugfix

and here:
http://piosolver.com/blogs/news/33449540-piosolver-1-3

The free version is slower than commercial one but it should be fast enough for any turn/river cases you may want to solve.

Enjoy!

Just in the process of getting a new laptop. Would these spec be enough to run Piosolver Pro?

Hi,

Yeah this is a top end laptop and about as good as you can get for a laptop.
Graphic card and display size don't matter for the solver at all of course so you can save money there if you are not a gamer.
We have a lot of users using those 4710HQ/4720HQ CPUs and they offer very decent performance, especially now, when PioSOLVER 1.4 is out.

Hello,

PioSOLVER-free got an update today. You can read more about it here:
http://piosolver.com/blogs/news/3707...to-1-4-version

Highlights:
-Even better performance, especially for trees with many bet sizes
-More features of Range Explorer - our very fast and powerful equity calculator and range analysis tool
-Vertical browsing and more tree building options

Have fun!

Is there a way to tell it to solve but for only a single iteration? I want to be able to node lock and find near ME strat in this manner.

I am not sure what you by "ME strat". There is a way to tell it to solve only by one iteration but as it's a very rare request we didn't make a button in the GUI
To do it:

1)build a tree
2)lock your nodes if you want
3)go to Tools->Solver->arbitrary command and type:
go 1 steps

in there.

In general go N steps runs the solver for N iterations. Take in mind that solver output is generated more often than every iteration. The dafaults are 25 iterations for flop trees, 50 iterations for turn trees and 100 iteration for river trees with additional constraint that at least 500ms has to pass since last output to a new one to be printed.

Hello,

We've updated PioSOLVER free to 1.5 version. While it's mainly a bugfix release it has some additional features, is a bit faster and behaves better on some difficult turn/river cases.
You can get it from our product page here:
http://piosolver.com/collections/fro...piosolver-free

I invite you to read more about it here:
http://piosolver.com/blogs/news/43559301-piosolver-1-5

Or visit our commercial forum thread here:
http://forumserver.twoplustwo.com/16...oldem-1516187/

Have fun!

Im trying to install the program and when I click the file there is a black dos window open and nothing happens, im also trying to install the PioViewer and its crash, am I doing something wrong or my laptop isnt strong enough to run it?
Also, do you think my PC with 8GB Kingston Savage RAM and i5 4590 will have any problems to optimaly run this software if i'll decide to purchase it? 8GB is enough to process complicated trees?
Thanks.

There should be a welcome string/copyright notice. This is a solver console and you don't need to use it.

The only limitation to run the free version is having 64bit operating system. If it crashes upon start it's almost certainly an issue with Net Framework, please download the newest stable one from Microsoft, here:

http://www.microsoft.com/en-us/downl....aspx?id=42642

This is a very decent CPU. I don't know about "optimally" (you can always get better hardware) but it should be quite decent. 8GB of RAM is a slight limitation if you want trees with many bet sizes but with recent memory optimizations you can really solve a lot having 5-6GB available.

It's hard to answer because the definition of "complicated" isn't clear. You can always build a bigger one. I personally almost never run trees beyond 8GB but there are certainly interesting cases between 8GB and 16GB. For some people even 64GB isn't enough as they run things like 5 sizes everywhere

Everything with one size will fit comfortably under 8GB. A lot of trees with 2 sizes at some points will fit as well. A lot of shortstack trees with 2 sizes everywhere will fit as well (although not all). Things with 3 sizes will not fit as a general rule (unless the ranges are really small).

I just installed the free version and I'm not getting any errors but I think it doesn't work because it shows %33 for every action with the whole range on different boards. Any ideas ?

Yeah, you need to solve the tree after building it by clicking "go" and then "stop" once the accuracy is good enough.
It's explained in some details here:

http://piosolver.myshopify.com/pages/quick-start-guide

Is this allowed with PokerStars open?

No. According to their new rules any software which can keep saved ranges isn't allowed that includes about every equity calculator out there let alone anything more sophisticated.

So i tried installing pio free version today and i got the following msg from antivirus( detected and intercepted trojan attacks) . Program c:..\ Pioviewer.exe Name : HEUR / QVM03.0.Malware.gen. Anyone with similar issues?

http://blog.mitechmate.com/remove-he...en-completely/

It seems it's not a problem on our side tbh. Either your computer is infected or it's a false positive. The free version is downloaded several hundred times a month and it's the same file for quite some time now.
Please make sure that's not a problem with your computer. If you would like to have some extra confirmation maybe ask people who are using the program already to scan it with an antivirus.
I've seen some false positives already (although from only one anti-virus vendor). That might happen because we are scanning for running processes names (because we have to assure the solver doesn't run along with Poker Stars to comply with their policy).

when I run the exe I get this error. Any solution?

It's almost surely a problem with a Net Framework version, please update to the newest stable one here:
http://www.microsoft.com/en-us/downl....aspx?id=42642

Let me know if that solved the problem!

U have mobile version??? I sure buy 1 ..

I am sorry I forgot about free_version thread for a while
We don't have a mobile versoin as of now. Turn/River solver is very sensible on mobile but a flop one would be too slow on current mobile hardware.
