Computer-implemented method for designing an industrial product modeled with a binary tree

A computer-implemented method for designing an industrial product modeled with a binary tree having leaf nodes representing basic volumes, non-leaf nodes representing binary commutative operation combining volumes, the method comprising the steps of: - performing a design operation triggering the adding or the removing of a leaf node; and - idealizing the binary tree, i.e. modifying the binary tree while maintaining the optimality of the tree by minimizing the number of weak leaf nodes, a weak leaf node being a leaf node such that, when removed, the resulting binary tree is not optimal anymore.
