This paper investigates gradient-type methods for solving optimization problems on Riemannian manifolds. In this approach, we utilize a search direction based on the gradient direction and employ a general non-monotone line search scheme to determine the stepsize at each iteration. This scheme encompasses several well-...

We propose a scaled projection neural network for solving quasi-variational inequalities in which the constraint set S(x)=m(x)+S depends on the state through a contraction mapping m that translates a fixed closed convex set S, while the projection is performed with respect to a fixed symmetric positive definite matrix...

We introduce two derivative-free spectral projection methods for large-scale monotone equations with convex constraints. The first, SOPP (Spectral Optimal-Perry Projection), selects its Perry parameter by minimizing the condition number of a symmetrized Perry matrix over its positive definite range, in place of the eig...
