Comparison of the solution sets (shown by parallel coordinates) obtained by the original IBEA (left) and IBEA working under BCE (right) on the 10-objective DTLZ2. Under the BCE framework, the Pareto criterion population helps the non-Pareto criterion population (here IBEA's population) diversify its solutions to the whole Pareto front.
Comparison of the solution sets (shown by parallel coordinates) obtained by the Pareto criterion evolution (left) and the bi-criterion evolution (right) on the 10-objective DTLZ5(2,10). Under the BCE framework, the non-Pareto criterion population helps the Pareto criterion population converge its solutions to the Pareto front.
