  "Description": "A collection of general optimization routines based on\nvariants of the One Side Cut Accelerated Random Search\n(OSCARS-II) algorithm (Price et al., 2020,\n<doi:10.1007/s10898-020-00928-6>). The main function ,\n'oscars()', performs black-box optimization of a general\n(including nonsmooth or discontinuous) function subject to\nsimple bounds on the unknowns. If all bounds are finite, oscars\nsearches globally. The main method implements a stochastic\ndirect search method and is derivative free. Testing shows the\nOSCARS-II algorithm usually finds extrema in fewer function\nevaluations than similar global derivative-free methods.",
