The purpose of this webservice is to infer parameters of an ELECTRE TRI Bouyssou-Marchant model, also called MR-Sort model. It takes in input the categories and criteria of the model and examples of assignments. The user should also specify several parameters of the metaheuristic: the size of the population of models (nmodels), the number of iterations to do with the heuristic adjusting the profiles, and the number of iterations (niter_heur) of the main loop (niter_meta). The metaheuristic will try to find a MRSort model which is compatible with the highest number of examples given in input.

The parameters of the metaheuristic. ‘nmodels’: the size of the population; ‘niter_heur’: the number of iterations of the heuristic; ‘niter_meta’: the number of iterations of the main loop.
The input value should be a valid XMCDA document whose main tag is <methodParameters>.
The solver to use. Currently CPLEX and GLPK are supported. In none specified, GLPK is used.
The input value should be a valid XMCDA document whose main tag is <methodParameters>.
The reference alternatives that are compatible with the profiles, weights and majority threshold computed by the webservice.
The returned value is a XMCDA document whose main tag is <alternatives>.
The profiles performance table of the profiles computed by the webservice.
The returned value is a XMCDA document whose main tag is <performanceTable>.
The set of criteria weights found by the webservice.
The returned value is a XMCDA document whose main tag is <criteriaValues>.
The category profiles computed by the webservice.
