optimbase.isfeasible {optimbase}

Check Point Estimate

Description

This function checks that the point estimate is consistent with the bounds and the non linear inequality constraints. It is usually called by optimbase.checkx0 to check initial guesses.

Usage

  optimbase.isfeasible(this = NULL, x = NULL)

Arguments

this

An optimization object.

x

The point estimate, i.e. a column vector of numerical values.

Details

Returns 1 if the given point satisfies bounds constraints and inequality constraints.

Returns 0 if the given point is not in the bounds.

Returns -1 if the given point does not satisfies inequality constraints.

Value

Return a list with the following elements:

this

The optimization object.

isfeasible

The feasibility flag, either -1, 0 or 1.
