چکیده انگلیسی:
Optimization is the process of finding and comparing feasible solutions and adopting the best
one until no better solution can be found. Because solving real-world problems often involves
simulations and multiobjective optimization, the results and solutions of these problems are
conceptually different from those of single-objective problems. In single-objective optimization
problems, the global optimal solution is the solution that yields the optimal value of the
objective function. However, for multiobjective optimization problems, the optimal solutions
are Pareto-optimal solutions produced by balancing multiple objective functions. The strategic
variables calculated in multiobjective problems produce different effects on the mapping
imbalance and the search redundancy in the search space. Therefore, this paper proposes a fitness
landscape ruggedness multiobjective differential evolution (LRMODE) algorithm with a
reinforcement learning strategy. The proposed algorithm analyses the ruggedness of landscapes
using information entropy to estimate whether the local landscape has a unimodal or multimodal
topology and then combines the outcome with a reinforcement learning strategy to determine the
optimal probability distribution of the algorithm’s search strategy set. The experimental results
showthat this novel algorithm can ameliorate the problem of search redundancy and search-space
mapping imbalances, effectively improving the convergence of the search algorithm during the
optimization process.
