Constructor.
Construct the problem from its dimension. Setting cub=clb=0 creates an instance of the original Luksan Vlcek equality constrained problem, example 5.1. Using clb < cub allows the obtain a problem formulation with inequality constraints.
[in] | N | problem dimension |
[in] | clb | lower bounds for the constraints. |
[in] | cub | upper bounds for the constraints. |
value_error | if N is smaller than 2, cub < clb |
