matlab实现一维小区定向信道锁定借用（BDCL）和FCA（固定信道分配）阻塞率比较的仿真程序，并对小区信道数对阻塞率的影响也进行了图形描述！(matlab plot to achieve one-dimensional directional channel locking to use (BDCL) and FCA (fixed channel allocation) Comparison of blocking rates of the simulation program, and the cell number of channels on the blocking probability is also studied in the graphic description!)

Traveling Salesman Problem (TSP) has been an interesting problem for a long time in classical optimization techniques which are based on linear and nonlinear programming. TSP can be described as follows: Given a number of cities to visit and their distances from all other cities know, an optimal travel route has to be found so that each city is visited one and only once with the least possible distance traveled. This is a simple problem with handful of cities but becomes complicated as the number increases.
