Here you have various, very old and untested, solutions and examples for Delphi. Last time I was dealing with this examples around 2008, so yeah -- they're quite old and pretty useless.

In this paper, a recurrent neural network is proposed using the augmented Lagrangian method for solving linear programming problems. The design of this neural network is based on the ...

By reformulating the linear multiplicative programming problem (LMP) as an equivalent nonconvex programming problem (EP), we present a new accelerating outcome space branch-and-bound algorithm for ...
