Pioneer Research on Mathematical Models and Methods for Physical Design

In the inaugural International Symposium on Physical Design (ISPD) at 1997, Prof. Te Chiang Hu has delivered the keynote address "Physical Design: Mathematical Models and Methods" [1]. Without any question, Prof. Hu has made a lot of foundational and profound contributions to physical design automation and to computer science and mathematics in general. This paper highlights several of Prof. Hu's pioneer works related to flow and cut in a flow network to commemorate his achievements.
