Optimisation methods

Implementation of one-dimensional, multi-dimensional optimization methods and conditional optimisation methods.

• cond_opt_methods.py - realisation of Kuhn Tucker and external penalty methods
• methods_opt0.py - realisation of optimisation methods of the 0th order of a one-dimensional function
• method_opt1.py - realisation of optimisation methods of the 1st order of a one-dimensional function
• method_opt2.py - realisation of optimisation methods of the 2nd order of a one-dimensional function
• methods_dim2.py - realisation of optimisation methods of multi-dimentional functions
