delay Fredholm integro-differential equations

Solving a class of nonlinear delay Fredholm integro-differential equations with convergence analysis

The main idea proposed in this article is an efficient shifted Legendre pseudospectral method for solving a class of nonlinear delay Fredholm integro-differential equations.  In this method, first we transform the problem into an equivalent continuous-time optimization problem and then utilize a shifted pseudospectral method to discrete the problem.
