A novel algorithm for the computation of Lucas sequences is proposed to improve the efficiency of cryptosystems based on it. By the introduction of pre-computation, the original Characteristic polynomial algorithm is modified to reduce the number of multiplication operations. The influence of window size on efficiency of the algorithm is also analyzed, and a optimization scheme is presented. In circumstances...
In this paper, A self-adaptive strategy to determine the control parameters of Differential Evolution (DE) is proposed based on the elaborate analysis of intrinsic structure. The projection information of fitness function in differential direction is used to get the scale factor, while the difference between the local distance and global search range is applied to determine the crossover rate. This...
In this paper, an improved Differential Evolution (DE) with a self-adaptive strategy to determine the control parameters is proposed to solve constrained real-parameter optimization, combined with the dynamic constraint-handling mechanism. It is implemented by restating the single-objective constrained optimization as a set of single-objective unconstrained problems and dynamically assigning to the...
