List of incrementByEps() Examples

Examples of incrementByEps()

com.barrybecker4.optimization.parameter.types.Parameter.incrementByEps()
increments the parameter a little bit in the specified direction. If we are already at the max end of the range, then we increment in a negative direction. @param direction either forward, or backward. @return the size of the increment taken

Examples of com.barrybecker4.optimization.parameter.types.Parameter.incrementByEps()

        double fwdFitness;
        double bwdFitness;


        Parameter p = testParams.get( i );
        // increment forward.
        delta.set(i, p.incrementByEps(Direction.FORWARD));


        fwdFitness = findFitnessDelta(optimizee, params, testParams);


        // revert the increment
        p.incrementByEps(Direction.BACKWARD);
