momst 0.1.1

  • Breaking change: all output column names are now in English to match the rest of the documentation and vignettes. If you were using version 0.1.0, update your code as follows:
    • objetivo_1, objetivo_2, objetivo_3 are now objective_1, objective_2, objective_3 in result$global_pareto and in the matrices returned by compute_objectives().
    • pesos_1, pesos_2, pesos_3 are now weight_1, weight_2, weight_3 in the data frames returned by generate_instance().
    • densidad is now density in the matrix returned by non_dominated_crowding().
  • Default axis labels of plot_pareto_front() are now “Objective 1” and “Objective 2” (previously in Spanish).

  • Four solver variants exposed through run_momst(): "base", "PR", "PLS", and "TS".
  • Support for 2 and 3 objective formulations.
