Abstract: To solve the optimization problem of fast forward path for multi-contour processing,an Improved Quantum Evolutionary Algorithm (IQEA) was proposed.The coding method of fast forward path based on two-dimensional Qubit Measurement Model (QMM) was designed,and the global searching guided by QMM was realized to generate the machining sequence of multi-segment.The decoding efficiency was higher in IQEA.By using the optimal sub-structure of multi-contour processing,the evaluation method of individual fitness based on dynamic programming algorithm was designed.The global searching ability of population was enhanced by the new dynamic rotation angle in quantum updating strategy.The simulation results and comparative experiments on classic benchmarks demonstrated the feasibility and effectiveness of the presented IQEA.

Key words: multi-contour processing, fast forward path, quantum-inspired evolutionary algorithm, rotation angle, dynamic programming algorithm
