The projection neural network, initially for monotone problems, now solves broader pseudomonotone variational inequalities and optimization problems. This recurrent neural network demonstrates stability and convergence for these complex mathematical challenges.

Area of Science:

  • Optimization
  • Applied Mathematics
  • Machine Learning

Background:

  • Recurrent neural networks, specifically projection neural networks, have been developed for monotone variational inequalities and convex optimization.
  • Existing methods are limited to specific classes of problems.

Purpose of the Study:

  • To extend the applicability of projection neural networks to pseudomonotone variational inequalities and pseudoconvex optimization.
  • To introduce and analyze a new concept of componentwise pseudomononicity.

Main Methods:

  • Theoretical analysis of projection neural network stability and convergence under pseudomonotonicity conditions.
  • Introduction and investigation of componentwise pseudomononicity.
  • Numerical simulations to validate performance.
