org.apache.commons.math.optimization.UnivariateRealOptimizer.optimize()

Find an optimum in the given interval.

An optimizer may require that the interval brackets a single optimum.

@param f the function to optimize. @param goalType type of optimization goal: either {@link GoalType#MAXIMIZE}or {@link GoalType#MINIMIZE}. @param min the lower bound for the interval. @param max the upper bound for the interval. @return a value where the function is optimum. @throws ConvergenceException if the maximum iteration count is exceededor the optimizer detects convergence problems otherwise. @throws FunctionEvaluationException if an error occurs evaluating the function. @throws IllegalArgumentException if min > max or the endpoints do notsatisfy the requirements specified by the optimizer.


        // endpoint is minimum
        double result = solver.optimize(f, GoalType.MINIMIZE, 3 * Math.PI / 2, 5);
        assertEquals(3 * Math.PI / 2, result, 70 * solver.getAbsoluteAccuracy());


        result = solver.optimize(f, GoalType.MINIMIZE, 4, 3 * Math.PI / 2);
        assertEquals(3 * Math.PI / 2, result, 70 * solver.getAbsoluteAccuracy());


    }
