Relaxation methods for optimal control problems [PDF]
Bulletin of Mathematical Sciences, 2020 We consider a nonlinear optimal control problem with dynamics described by a differential inclusion involving a maximal monotone map A : ℝN → 2ℝN. We do not assume that D(A) = ℝN, incorporating in this way systems with unilateral constraints in our ...

Radiosity and relaxation methods [PDF]
IEEE Computer Graphics and Applications, 1994 To date, there has been some confusion in the computer graphics community about how the progressive radiosity (PR) method relates to standard numerical methods for solving linear systems of equations. We show that PR is actually equivalent to the combination of two numerical analysis techniques known as Southwell relaxation and Jacobi iteration.

Problem Relaxation Methods for Quantum Minimum Fill-in Algorithm
IEEE Access, 2023 Current quantum annealing and quantum-inspired annealing devices have many usage limitations and are difficult to apply to real-scale problems. In particular, a major hardware limitation is the limited number of available variables (qubits).

Relaxation Methods for Linear Programs [PDF]
Mathematics of Operations Research, 1987 In this paper we propose a new method for solving linear programs. This method may be viewed as a generalized coordinate descent method whereby the descent directions are chosen from a finite set. The generation of the descent directions are based on results from monotropic programming theory.

The mathematical model of quantum dots pair orientation under laser radiation field
Компьютерная оптика, 2022 One approach for the formation of structures with complex geometries at the nanoscale is the step-by-step assembly. In this case, it is necessary to be able to estimate the time required to establish orientational equilibrium for a preformed pair of ...

Boundedness Theorems for the Relaxation Method [PDF]
Mathematics of Operations Research, 2005 A classical theorem by Block and Levin (Block, H. D., S. A. Levin. 1970. On the boundedness of an iterative procedure for solving a system of linear inequalities. Proc. Amer. Math. Soc. 26 229–235) states that certain variants of the relaxation method for solving systems of linear inequalities generate bounded sequences of intermediate solutions, even
