Choose initial path for LCP

2008-02-19T01:30:18Z

The Lemke(-Howson) method starts with an arbitrary selection of an initial pivot. Expose functionality to allow this to be selected by the user.

Clarify output of command-line programs

2008-02-18T12:19:56Z

The output of some command-line programs may be confusing. For instance, gambit-enummixed always outputs the equilibria in reduced strategic form, even when the original game is passed as extensive form.

Not sure if there's an easy workaround for this, or whether it's time to get serious about file formats.

Stop gambit-lcp after N equilibria

2008-01-30T14:02:15Z

We used to have a feature to terminate gambit-lcp after finding a pre-specified number N of equilibria. This should be implemented as a command-line option.

Refactor tableau classes

2007-12-31T21:33:02Z

Tableau and pivoting code appears in several locations in Gambit (LP, LCP, eliminating dominated strategies by mixtures). Refactor these into one location that can be more conveniently accessed by applications.

Map API

2007-12-31T21:31:50Z

The Gambit::Map API was designed in the mid-1990s before exceptions were part of the C++ standard. As a result, the class uses a kludgey "default" which is returned when a requested key is not defined. In addition, some function names are not consistent with more recent developments. The API should be modernized to use exceptions and operator overloading, and work towards consistency with other comparable classes in, e.g., BOOST.

Tab across outcomes in extensive games

2007-12-26T21:39:14Z

Suggested feature. I typically make the tree structure first, and then
at the end, fill out the payoffs. I click on the top leaf node and fill in
the payoff information, using "Tab" to move between payoffs for each
player. After filling the payoffs for all the players at that leaf node,
it would be nice to be able to "Tab" to the next leaf node's payoff
textboxes, like how "Tab" in a spreadsheet or table will move you to the
next line to fill out once at the end of the current line. It would save
time from having to then move to the mouse, and double click the next leaf
node's payoff area.

Copying trees into new information sets

2007-12-26T21:37:16Z

Suggested feature. Use a different button or button combination
(Ctrl+Alt?) for copying without putting them in the copied subtree in the
same information set as the source subtree. Can avoid having to use the
reveal feature so much in highly symmetric games of perfect information.

Export format for normal forms

2003-12-11T22:25:58Z

A useful export format for normal form game tables
would be the LaTeX macro package Martin Osborne has
created for games:
http://www.chass.utoronto.ca/~osborne/latex/

Direct LaTeX tabular output might also be nice.

Doing this for extensive form games would be harder. :)
