Tīmeklis2024. gada 3. febr. · Lagrangian relaxation is an optimization technique made famous in 1971 by Held and Krap when they addressed the travelling salesman problem. The main idea behind the technique is to separate the constraints of a problem between “easy” and “hard” constraints, and then add the “hard” constraints to the objective … TīmeklisThe Lagrangian stretching field is a type of Lagrangian coherent structure (LCS) (27– 29) that has found numerous applications in geophysical flows (29), active and passive particle transport (30, 31), and chemical reacting flows, but its use in non-Newtonian flows has been limited (32). The stretching field quantifies the relative deformation of
