[Abstract]:In order to solve the problem of task scheduling in heterogeneous multi-core systems by genetic algorithm (GA), it is easy to produce premature phenomenon and the ability of local optimization is poor, so the local search algorithm is combined with genetic algorithm (GA).A hierarchical hybrid local search genetic algorithm is proposed to solve the task scheduling problem of heterogeneous multi-core systems.In this algorithm, a new hierarchical optimization strategy is proposed to generate the initial population. In the mutation operation, some individuals are designed to optimize the 3-opt mutation, and the improved Lin-Kernighan algorithm is used to optimize the excellent individuals in the population.Simulation results show that the hierarchical hybrid local search genetic algorithm can efficiently obtain high quality solutions to the task scheduling problem of heterogeneous multi-core systems.
