If the book G.Giraud addresses most aspects of game theory, I admit it was difficult to follow. I'm thinking that his style is not suited to the presentation of this theory. It makes extensive use mathematical vocabulary, not always introduce sprinkled about his touches of humor
not always successful / butt, and peppers his anecdotes about historical war, Latin quotations ... all is reminiscent of gloubi-boulga.
Wanting to present the theory in simple words is a good thing, but it's a difficult thing, and if that is the purpose of the work, so we had to stick to it! If not, why not use the classical definition-theorem presentation (+ possibly demonstration) ??
The back cover starts and "Both warn the reader: This book is neither a math class or a manual for making a fortune in casinos [...]". What is it then? Indeed, definitions and theorems are not introduced conventionally, but they are there, in the text. So, impossible to navigate.
Ex p128: "Each of the two pure balance strategic stability has all the virtues that can be expected, and each Pareto-dominates the Nash equilibrium Mixed Finally the convex hull of those two pure equilibria coincides with. all Pareto optima ".
Woe to you if you have any doubt about what "pure" or "mixed" you will hardly find definitions. Worse, if you do not know what the "convex hull balances", that is not explained, you're doing !!
