| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary This paper introduces a novel hierarchical framework for optimal transport (OT) using string diagrams. The approach reduces complex hierarchical OT problems to standard OT problems, enabling efficient synthesis of optimal transportation plans. Algebraic compositions of cost matrices effectively model hierarchical structures. The framework also handles adversarial situations with multiple choices in the cost matrices, providing a polynomial-time algorithm for a relaxation of the problem. Experimental results demonstrate the efficiency and performance advantages of this proposed algorithm over the naive method. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary Imagine trying to move people or things from one place to another in an efficient way. This paper presents a new way to do that, using special diagrams called string diagrams. The idea is to break down big problems into smaller ones and solve them step by step. This makes it easier and faster to find the best way to transport things. The researchers also tested this method with different scenarios and found that it works better than just doing it one step at a time. |
