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:

A. Messac, A. Ismail-Yahaya and C.A. Mattson. The normalized normal
constraint method for generating the Pareto frontier structural and
multidisciplinary optimization Volume 25, Number 2 (2003), 86-98.

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

4) CostFuntion.m
The cost function to optimize
