查询词典 optimality principle

However, for hill-climbing strategies to be guaranteed to find the global optimum the optimality landscape must be unimodal. Moreover, research has demonstrated that multiple maxima exist under the maximum likelihood principle. Therefore, hill climbing based evolutionary tree reconstruction methods often return local optima.
