Description

technical field [0001] The invention relates to a multi-core parallel ant colony design method based on TBB (Thread Building Blocking), which belongs to the field of computer simulation and algorithm optimization. Background technique [0002] Combinatorial optimization problems of discrete systems are often encountered in actual production, such as task allocation, job scheduling, path planning, network routing, data mining, life science computing, etc. The rapid increase of is known as the NP complexity problem. [0003] Since Dorigo M proposed the ant colony algorithm, the algorithm has achieved relatively good results in solving this type of problem, but if the scale of the problem continues to expand, the time consumed by the serial ant colony algorithm based on a single CPU will increase rapidly, and often It cannot meet people's real-time computing needs. How to obtain a simple and applicable method to improve the running time efficiency of ant colony algorithm will...

Problems solved by technology

[0004] An effective way to improve the operating efficiency of the ant colony algorithm is parallel design. Most of the existing parallel ant colony algorithms are implemented based on MPI (Message Passing Interface), but MPI design of parallel algorithms is relatively cumbersome, especially when dealing with data sharing and data During the exchange process, it is usually only suitable for parallel ant colony algorithms designed by professional programmers on computer clusters
