1d:T757,# Generation of a new population of parameter sets following the five rules of caRamel generates a new population of parameter sets following the five rules of caRamel ```r newXval(param, crit, isperf, sp, bounds, repart_gene, blocks, fireworks) ``` ## Arguments - `param`: : matrix [ Nvec , NPar ] of parameters of the current population - `crit`: : matrix [ Nvec , NObj ] of associated criteria - `isperf`: : vector of Booleans of length NObj, TRUE if maximization of the objective, FALSE otherwise - `sp`: : variance a priori of the parameters - `bounds`: : lower and upper bounds of parameters [ NPar , 2 ] - `repart_gene`: : matrix of length 4 giving the number of games to be generated with each rule: 1 Interpolation in the simplexes of the front, 2 Extrapolation according to the directions of the edges "orthogonal" to the front, 3 Random draws with prescribed variance-covariance matrix, 4 Recombination by functional blocks - `blocks`: : list of integer vectors containing function blocks of parameters - `fireworks`: : boolean, TRUE if one tests a random variation on each parameter and each maximum of O.F. ## Returns xnew : matrix of new vectors [ sum(Repart_Gene) + eventually (nobj+1)*nvar if fireworks , NPar ] project_crit: assumed position of the new vectors in the criteria space: [ sum(Repart_Gene)+ eventually (nobj+1)*nvar if fireworks , NObj ]; ## Examples ```r # Definition of the parameters param <- matrix(rexp(100), 100, 1) crit <- matrix(rexp(200), 100, 2) isperf <- c(FALSE, FALSE) bounds <- matrix(data = 1, nrow = 1, ncol = 2) bounds[, 1] <- -5 * bounds[, 1] bounds[, 2] <- 10 * bounds[, 2] sp <- (bounds[, 2] - bounds[, 1]) / (2 * sqrt(3)) repart_gene <- c(5, 5, 5, 5) fireworks <- TRUE blocks <- NULL # Call the function res <- newXval(param, crit, isperf, sp, bounds, repart_gene, blocks, fireworks) ``` ## Author(s) Fabrice Zaoui1e:T49a,M7.49933 0.25C3.49635 0.25 0.25 3.49593 0.25 7.50024C0.25 10.703 2.32715 13.4206 5.2081 14.3797C5.57084 14.446 5.70302 14.2222 5.70302 14.0299C5.70302 13
