Biological particle cluster construction method based on BCCA optimization model

Abstract

The invention provides a biological particle cluster construction method based on a BCCA optimization model. The method comprises the steps: acquiring the number of particles existing in a three-dimensional space and the particle size of each particle; constructing a three-dimensional model; setting and calling a lowbit function, and calculating an expected cluster body number N; judging whether the number Nc of current cluster bodies in the three-dimensional model is equal to 1 or not; determining currently existing cluster bodies in the three-dimensional model, and performing collision processing when the cluster bodies meet corresponding collision conditions and collide with one another; determining a current cluster body number Nc; and outputting a three-dimensional distribution diagram of the particles in the current cluster body, and outputting the three-dimensional distribution mode of the particles in the current cluster body as a result. According to the method provided by the invention, a better extinction material structure can be formed, and the preparation of the extinction material with stronger extinction characteristic is facilitated.
