Abstract Simplicial partitions are suitable to divide a bounded area in branch and bound. In the iterative refinement process, a popular strategy is to divide simplices by their longest edge, thus avoiding needle-shaped simplices. A range of possibilities arises when the number of longest edges in a simplex is greater than one. The behaviour of the search is different depending on the selected longest edge. In this work, we investigate the importance of the rule to select an edge.
