We also performed model regularization--when using a full differential fourth -order equation we dealt with a redundant equation, which caused deterioration of functional convergence to a minimum and, as a result, considerable increase of a number of iterations.
This topological representation readily maps to its mathematics through the powerful Maple engine and uses several simplification tools to remove redundant equations and reduce input to a minimal equation set that will accurately represent the system.
