- This error occurs when the primal and dual objective value of the
- conic program associated with a linear game do not agree. By
- construction, every conic program derived from a linear game must
- have a solution and the same objective value (the "value of the
- game") is shared by both players.
-
- Each instance of this class will know the two mismatched values, and
- its ``message`` field will explain why they can't be so.
+ Every linear game has a solution (this follows from a general
+ min-max theorem). If we can't solve the conic program associated
+ with a linear game, then something is wrong with either the model of
+ the input.
