Method Detail

solve

public double solve(int maxEval,
                    DifferentiableUnivariateFunction f,
                    double min,
                    double max)
             throws TooManyEvaluationsException
Deprecated. 
Find a zero near the midpoint of min and max.

Specified by:
solve in interface BaseUnivariateSolver<DifferentiableUnivariateFunction>
Overrides:
solve in class BaseAbstractUnivariateSolver<DifferentiableUnivariateFunction>
Parameters:
f - Function to solve.
min - Lower bound for the interval.
max - Upper bound for the interval.
maxEval - Maximum number of evaluations.
Returns:
the value where the function is zero.
Throws:
TooManyEvaluationsException - if the maximum evaluation count is exceeded.
NumberIsTooLargeException - if min >= max.

doSolve

protected double doSolve()
                  throws TooManyEvaluationsException
Deprecated. 
Method for implementing actual optimization algorithms in derived classes.

Specified by:
doSolve in class BaseAbstractUnivariateSolver<DifferentiableUnivariateFunction>
Returns:
the root.
Throws:
TooManyEvaluationsException - if the maximal number of evaluations is exceeded.
