Algorithms -- optimal algorithm for collision probabilities calculation in 3-D rectangular-cylindrical geometries

Abstract-In 3D geometry, the problems of the collision probability (CP) method related to high memory and execution time requirements increase rapidly with the number of regions. The paper shows an attempt to minimise these requirements at the level of probability matrix evaluation. The mixed method (MM) for tracking and probability calculations, and an improved module of CPs contribution calculation, were developed. Finally, the new schema has approximately 50% reduced memory and execution time compared to the old version
