Two model\nstructures are available: a compact two-dimensional mapping and\na full mapping with one fewer dimension than the number of\ncomponents. Both models support parameter estimation, point\nprediction, and plug-in predictive uncertainty. Input checks\nvalidate the sequence data and apply consistent scaling to the\nquantitative inputs. Computationally intensive covariance and\ngradient calculations are implemented in C++ with 'Rcpp'.\nInitial-design functions combine a space-filling Latin\nhypercube with sequence permutations. The sequence portion can\nbe generated randomly or optimized with simulated annealing or\nspace-filling threshold accepting. Expected improvement can be\noptimized over both parts of the input, and a sequential\ninterface supports Bayesian optimization of an expensive\nuser-supplied objective. An integrated workflow can generate\nthe initial design, evaluate the objective, and continue the\nsequential search in one call. The model was introduced by Xiao\net al.
