//
// fct cost function fct(x,USERDATA) to minimize
// VTR "Value To Reach". DiffEvol will stop its minimization
// if either the maximum number of iterations "itermax"
// is reached or the best parameter vector "optarg"
// has found a value f(optarg,y) <= VTR.
// D number of parameters of the objective function
// XVmin vector of lower bounds XVmin(1) ... XVmin(D)
// of initial population
// *** note: these are not bound constraints!! ***
// XVmax vector of upper bounds XVmax(1) ... XVmax(D)
// of initial population
// USERDATA problem data vector which is passed transparently to
// the cost function fct
// NP number of population members
// itermax maximum number of iterations (generations)
// F DE-stepsize F from interval [0, 2]
// for strategies 3 and 8 this has 2 components
// CR crossover probability constant from interval [0, 1]
// strategy 1 --> DE/best/1/exp 6 --> DE/best/1/bin
// 2 --> DE/rand/1/exp 7 --> DE/rand/1/bin
// 3 --> DE/rand-to-best/1/exp 8 --> DE/rand-to-best/1/bin
// 4 --> DE/best/2/exp 9 --> DE/best/2/bin
// 5 --> DE/rand/2/exp else DE/rand/2/bin
// Experiments suggest that /bin likes to have a slightly
// larger CR than /exp.
// report intermediate output will be produced after "report"
// iterations. No intermediate output will be produced
// if report is < 1
//
// The first four arguments are essential (though they have
// default values, too). In particular, the algorithm seems to
// work well only if [XVmin,XVmax] covers the region where the
// global minimum is expected. DE is also somewhat sensitive to
// the choice of the stepsize F. A good initial guess is to
// choose F from interval [0.5, 1], e.g. 0.8. CR, the crossover
// probability constant from interval [0, 1] helps to maintain
// the diversity of the population and is rather uncritical. The
// number of population members NP is also not very critical. A
// good initial guess is 10*D. Depending on the difficulty of the
// problem NP can be lower than 10*D or must be higher than 10*D
// to achieve convergence.
// If the parameters are correlated, high values of CR work better.
// The reverse is true for no correlation.
//
// default values in case of missing input arguments:
// VTR = 1.e-6;
// D = 2;
// XVmin = [-2 -2]';
// XVmax = [2 2]';
// y=[];
// NP = 10*D;
// itermax = 200;
// F = [0.8;0.6];
// CR = 0.5;
// strategy = 7;
// report = 10;
//
// Cost function: function result = f(x,y);
// has to be defined by the user and is minimized
// w.r. to x(1:D).
//
// Example to find the minimum of the Rosenbrock saddle:
// ----------------------------------------------------
// Define f.m as:
// function result = f(x,y);
// result = 100*(x(2)-x(1)^2)^2+(1-x(1))^2;
// end
// Then type:
//
// VTR = 1.e-6;
// D = 2;
// XVmin = [-2 -2];
// XVmax = [2 2];

// devec is a vectorized variant of DE which, however, has a
// propertiy which differs from the original version of DE:
// 1) The random selection of vectors is performed by shuffling the
// population array. Hence a certain vector can't be chosen twice
// in the same term of the perturbation expression.
//
// Due to the vectorized expressions DiffEvol executes fairly fast
// in MATLAB's interpreter environment.
