Simple Multistart #447

Open ScottDelbecq opened 2 years ago

ScottDelbecq commented 2 years ago

This PR aims at providing a multistart optimization feature configurable from the configuration file. The Design of Experiment method used is a Latin Hypercube Sampling method. Here is an example of the syntax in the optimization section of the configuration file:

optimization:
  options:
    - multistart: true
      samples: 10
      criterion: maximin
      num_proc: 4
  design_variables:
    - name: x
      lower: 0
      upper: 10
    - name: z
      lower: 0
      upper: 10
  constraints:
    - name: g1
      upper: 0
    - name: g2
      upper: 0
  objective:
    - name: f

The num_proc field is the number of processors to use for multiprocessing but is not yet used and will be implemented in a later PR.
