COBYLA an algorithm for minimizing a function of many variables. The method is derivatives free (only the function values are needed) 
and take into account constraints on the variables. The algorithm is described in:

  > M.J.D. Powell, "A direct search optimization method that models the objective and constraint functions by linear interpolation," in 
  > Advances in Optimization and Numerical Analysis Mathematics and Its Applications, vol. 275 (eds. Susana Gomez and Jean-Pierre Hennart), 
  > Kluwer Academic Publishers, pp. 51-67 (1994).

## cobyla 0.2.x


COBYLA C code has been translated to Rust using [c2rust](https://github.com/immunant/c2rust) then manually edited.

## cobyla 0.1.x


Rust wrapper for COBYLA optimizer (COBYLA stands for Constrained Optimization BY Linear Approximations). 
COBYLA C code was copied from [here](https://github.com/emmt/Algorithms/tree/master/cobyla)
