这里考虑的是均衡，特别是那些解决非合作博弈的均衡。重点是进化稳定性、凹性和单调性之间的联系。证明了在梯度动力学下，演化稳定点是局部吸引子。这种动力在反映对个人进步的追求的同时，可能包含短视、不完善的知识和有限的理性/能力。
Considered here are equilibria, notably those that solve noncooperative games. Focus is on connections between evolutionary stability, concavity and monotonicity. It is shown that evolutionary stable points are local attractors under gradient dynamics. Such dynamics, while reflecting search for individual improvement, can incorporate myopia, imperfect knowledge and bounded rationality/competence.
