The strategy application is invoked as follows:
java com.lotspiech.poker.strategy.Strategy strategy-file "name of machine" [-dump dump-file]
You use this application to calculate the optimal strategy and the net return of a given video poker machine. This application runs through all possible initial deals, and, for each deal, runs through all 32 possible discards to find the best discard. It writes the correct discard in the strategy file in a binary form and then displays the net return, i.e., the casino's cut. These calculations take a long time--at least over night, usually. The program is self-checkpointing. If your computer crashes, you can start the program again on the same strategy file and it will pick up where it left off. You can use this trick to display the net return again, too, once the strategy is completely calculated.
The program reads the games.txt file in the current directory to find the payout table for the machine you specified in the command line. The games.txt file is human-readable and you can edit it to add a new machine you have found. I wouldn't mind if you send your addition to lotspiech@users.sourceforge.net so I can update it here.
The -dump option prints the optimal all-hand strategy in a
human-readable form, in addition to the binary strategy file. This is a
huge file, and not very useful if you are trying to create a workable strategy
for casino use. For that purpose, I have another tool, the "rules
application".
