I was thinking more like
http://www.gametheory.net/dictionary/games/GameofChicken.html
> James and I wondered about this one for a while and are also agnostic
about it. I think it could be nice to have it as just `game_theory.[tab]`
so that potentially we would get `game_theory.Nim` as well as
`game_theory.PrisonersDilemma` but at the same time it might be more
organised to seperate things out (in which case we should probably also
rename the `catalog.py` file to `normal_form_game_catalog.py`. Let us know
what you think: very happy either way.
Then better to plan for the future, eh?
Minor, many very minor points because I have nothing else to complain
about:
* `an often used v` -> `An often used v`
* `There is a single Nash equilibria` -> `There is a single Nash
equilibrium`
* There are several other instances of this, I believe, e.g.
{{{
+ A coordination game is a particular type of game where the pure Nash
+ equilibria
}}}
so please be careful on the plural/singular here.
* `if the defining inequality is not` -> `if the defining inequalities are
not`
* I think most of the things like
{{{
Return a Battle of the Sexes game
}}}
should be
{{{
Return a Battle of the Sexes game.
}}}
* `Chicken: Anti coordination game: Normal Form Game` seems not to jive
with the usual `Battle of the sexes - Coordination game: Normal Form Game`
format. I don't know that I like either but I understand the dilemma
here.
* Game theory question.
{{{
+ An anti coordination game is a particular type of game where the pure
Nash
+ equilibria is for the players to pick different strategies (or
equivalent)
+ strategies.
}}}
What does that mean - do they pick different ones or not? I have a
feeling you cut and pasted from `CoordinationGame` here.
* The numbers for `HawkDove` and `Pigs` seem somewhat arbitrary. Maybe
they could at least be scaled (optionally)? What do you think?
* `like a Hawk of a Dove.` -> `like a Hawk or a Dove.`
* The numbers don't work out right for `Pigs` without additional
explanation. See [http://managerialecon.blogspot.com/2011/11/john-
mcmillans-rational-pigs-puzzle.html here] where it's explained a bit
better why 3.5 and 1.5 means the subservient pig gets 1/3 of the food! I
was stumped by that for a while.
* `Return a Matching pennies game` -> `Return a Matching Pennies game`
* Don't forget the web link for RPSLS like you did elsewhere
* `both players naming the smallest possible value` -> `both players
naming the smallest possible value.`
* The following paragraph is too far indented.
{{{
+ Note that this command can be used to create travellers dilemma
for a
+ different maximum value of the luggage. Below is an
implementation
+ with a maximum value of 5::
+
}}}
* `Rock crushes scissors` -> `Rock crushes Scissors`
