The following code shows the object-oriented design of the library by a simple example of minimization.LogGamma logGamma = new LogGamma; // the log-gamma function
BracketSearchMinimizer solver = new BrentMinimizer; // precision, max number of iterations
UnivariateMinimizer.Solution soln = solver.solve; // optimization
double x_min = soln.search; // bracket =
System.out.println = %f", x_min, logGamma.evaluate));
