optimbase-package {optimbase}

R port of the Scilab optimbase module

Description

The goal of this package is to provide a building block for a large class of specialized optimization methods. This packages manages:

• the number of variables,

• the minimum and maximum bounds,

• the number of non linear inequality constraints,

• the cost function,

• the logging system,

• various termination criteria,

• etc...

Features The following is a list of features the optimbase toolbox currently provided:

• Manage cost function

  • optionnal additionnal argument

  • direct communication of the task to perform: cost function or inequality constraints

• Manage various termination criteria, including:

  • maximum number of iterations,

  • tolerance on function value (relative or absolute),

  • tolerance on the vector of estimated parameter x (relative or absolute),

  • maximum number of evaluations of the cost function,

• Manage the history of the convergence, including:

  • history of function values,

  • history of optimum point.

• Provide query features for

  • the status of the optimization process,

  • the number of iterations,

  • the number of function evaluations,

  • function value at initial point,

  • function value at optimal point,

  • the optimum parameters,

  • etc...
