In this thesis, we propose efficient and effective algorithms for solving global optimization single problem and directed acyclic graph scheduling problem. In particular, the main contributions of this thesis can be briefly summarized as follows:
(1)The author proposed a new algorithm called Mean-Search Operator (MSO). The purpose of this algorithm is to find a solution neither too close nor too far away from the initial solution in the solution space. This algorithm helps to avoid missing out any solutions in the exploitation and exploration process of the solution space that previous algorithms have not reached.
(2)The author proposed a hybrid algorithm (MPC) based on particle swarm, chemical reaction optimisation and new efficient Mean-search operator for single objective optimisation problems. In addition, three versions of this operator, which use different constraints, are introduced.
(3)The author proposed three new operators (Molecule, Neighbor, and CalcPE) to resolve the Directed acyclic graph scheduling problem. Moreover, based on some of the superiority of the CRO, GA algorithm, the author rebuilt two operators (Inter-mole and On-wall operator) of the CRO algorithm and the Crossover operator of the GA algorithm to fit with this problem and to reach better results.
(4)The author proposed a hybrid algorithm (HGCRO) for DGA scheduling based on CRO and GA for heterogeneous computing. The author designed two local search operators based on the Neighbor operator to suit for scheduling problem. Simulations results have shown that the proposed algorithms have a superior performance to prior methods.
