ABSTRACT A mixture of techniques is presented in order to solve The Physical Traveling Salesperson Problem for GECCO-2005 Competition. The method of solution is divided in two principal parts. The first part is to find a good tour using the Classic
Permutation-based combinatorial optimization problems have very wide application. Aim of the study is to design a real coding mechanism for evolutionary computing to solve permutation-based COPs. A real adjacency matrix-coded differential evolutionar
A back-illuminated mesa-structure InGaAs/InP charge-compensated uni-traveling-carrier (UTC) photodiode (PD) is fabricated, and its saturation characteristics are investigated. The responsivity of the 40-\mu m-diameter PD is as high as 0.83 A/W, and t
2 Based on quantum mechanics, a traveling ballot scheme with anonymity and secrecy is introduced to realize voting. By searching the objects in large amount of data bases, every voter may cast votes to his desired candidates. Therefore, the proposed
The Gaussian doping is used to optimize the performance of InP/InGaAs uni-traveling-carrier photodiode (UTC-PD) in this letter. The UTC-PD structure is modeled with drift-diffusion approach and the comparisons of the characteristics for four UTC-PDs
