Ding-Zhu Du (born May 21, 1948) is a Professor in the Department of Computer Science at The University of Texas at Dallas. He has received public recognition when he solved two long-standing open problems on the Euclidean minimum Steiner trees, the proof of Gilbert–Pollack conjecture on the Steiner ratio of the Euclidean plane, and the existence of a polynomial-time heuristic with a performance ratio bigger than the Steiner ratio. The proof of Gilbert-Pollak's conjecture on Steiner ratios was later found to have gaps, thus leaving the problem unsolved.
