In this game, any coalition-proof Nash equilibrium does not exist due to the fact that all pure strategies have at least one self-enforcing deviation.
The definition of a self-enforcing deviation is recursive.
In fact, the set of correlated equilibria contains those equilibria from which no coalition has a self-enforcing deviation, making all members better off.
In a game with more than one player, a combination strategy is coalition-proof Nash equilibrium if no sub-coalition has a self-enforcing deviation that makes all its members better off.
But these need enforcing.
enforcing the condition [14].
enforcing the normalization condition.
Although the exact 180° relationship in that system was likely enforced by crystallographic symmetry, the deviation from the ideal 166° angle in actin filaments suggested that the FH2 domain might exert strain on the filament.
The gradient of the control variable corrects the convective flux in the nonlinear state equation so as to enforce mass conservation while minimizing deviations from the target state.
Recognizing this problem, Bernheim et al. [44] introduced the notion of coalition-proof Nash equilibrium, which requires only that an agreement be immune to improving deviations which are self-enforcing.
Deviation from the nation's enforced Sunni faith is harshly punished, according to Human Rights Watch.
