Normalized Normal Constraint (NNC) algorithm for multi-objective optimization

This code implements a NNC algorithm for multi-objective optimization.

This Toolset comprises of the following files:

1) NNCparam.m

Generates the required parameters to run the NNC optimization algorithm.

2) NNC.m

Runs the optimization algorithm. This code implements the NNC algorithm for 2 and 3 objectives as described in:

3) OPTroutine.m
Implements the optimization routine for NNC algorithm.

4) CostFuntion.m
The cost function to optimize
