Comments, Follow-up work, Updates and Corrections
The package is availabe from the official CRAN repository.
The following is a list of updates and versions:
06.12.2022 (version 2.0.2)
- CHANGE: updated manual pages by adding new (recent) literature references and revising explanations
09.05.2022
09.06.2021 (version 2.0.1)
- BUGFIX: added tolerance parameter "tol" to function mgss, to account for roundoff errors behind the 5th digit after the comma when solving the linear programs
05.05.2021:
- BUGFIX: in some cases, numeric roundoff errors encountered internally in the constraints of the LPs made the linear programs infeasible. Added an optional tolerance parameter "tol", defaulting to zero for exact solutions, but usable to fix the roundoff errors if needed.
04.2020
- CHANGE: replaced fictitious play to compute approximate security strategies by an exact algorithm using linear programming. This will be version 2.0.0 of the package, pending for release over CRAN. It is no longer downwards compatible regarding the function
mgss to code using version 1.x.x. Thanks to Ali Alshawish and Vincent Bürgin for reporting the convergence issues with fictitious play that led to this change.
- FEATURE: added support for real-valued multi-criteria games that use lexicographically ordered payoffs
- FEATURE: extended the function
disappointmentRate to take matrix games over the reals and compute the disappointment rate directly for them, or for a given equilibrium therein
- FEATURE: added convenience function for extraction and replacement of parts of a game's payoff structure (in the usual R-syntax
x[i,j,..] <- replacement, or x[i,j,k] for extraction)
- FEATURE: added an option
cleanUp = FALSE to plot.mosg to retain the SVG file for subsequent use elsewhere (e.g., in papers)
11.2019:
- BUGFIX: error in
moment function; thankfully submitted (with correction) by Ali Alshawish
07.2019:
- FEATURE: added vignette paper (displayable via
RShowDoc("vignette", type="pdf", package="HyRiM"))
09.2018:
- BUGFIX: function
mosg incorrectly handled the parameter setting byrow = FALSE
- BUGFIX:
moment was on categorical distributions incorrectly using range rather than supp
07.2018:
- BUGFIX: games with numeric payoffs fail if one of the payoffs is an integer power of 10 (so that the internal distributions become degenerate in this case)
07.2018
- BUGFIX:
preference function incorrectly ignored all but the last goal
04.2018
- FEATURE: added "disappointment rate" function
02.2018
- BUGFIX: preference function returned wrong results for relations between numbers and distributions
01.2018
- BUGFIX: preference among discrete distributions with different ranges but equal support was occasionally computed incorrectly
08.2017
- FEATURE:
plot.mosg now takes arguments xlim and ylim to make all plots comparable by identical axes ranges
- BUGFIX: improvement to the implementation of density (now returns zero only for categories as they are specified; nothing more)
- BUGFIX:
print.mosg did not list the goals by name (now does)
08.2017
- BUGFIX: density, when applied to continuous distributions, returned zero for vector arguments in some occasions
07.2017
- BUGFIX:
range now properly updated after smoothing a density (previously, the range was set based on the data, but not updated after smoothing, which caused errors when moments were computed (visible by warning messages))
- FEATURE: if loss distributions with empty categories are supplied, the error now tells where the problem occurred in the game (row, column and goal)
