Solvers

This package has solvers for constrained and unconstrained L1 minimization, which is useful for compressed sensing. u = COORDL1BREG(A,f,lambda) solves the minimization problem min_u ||u||_1 subject to A*u = fwhere A is an MxN matrix and f is a vector of length M. Input lambda is a positive...

Multi-Knapsack solver by two stochastic solvers : i) by Cross-Entropy Method and ii) by Botev-Kroese Method for the following problemmax S(X)=(p^{t}X) st. WX

It is desired for modern process systems to achieve optimal operation. However, operation at a pre-designed nominally optimal point may not necessarily be actually optimal due to realtime disturbances, measurement and control errors and uncertainties. Self-optimizing control aims to tackle this...
