Christian Posthoff [1]
Christian Posthoff,
a German mathematician and computer scientist, Ph.D. in 1975 from Leipzig University, Dr.-Ing. habil. in 1979 from Chemnitz University of Technology, promoting to assistant professor for logic design, since 1983 full professor for CS at TU Chemnitz, and since 1994 professor of CS at the Department of Mathematics and Computer Science [2], University of The West Indies, St. Augustine, Trinidad and Tobago. Beside other things, his research interest covers Fuzzy Logic and the satisfiability problem (SAT), also applied to computer chess. In the 80s, Christian Posthoff was co-author of various computer chess books. In 2012, as now retired professor [3], along with Bernd Steinbach, he solved a 4-coloring of 17x17 grids without monochromatic rectangles [4] [5] [6] [7] [8].

A Quote from his biography [9] :
An independent direction of research activities within AI, investigations of computer chess and other strategic games, arose from my love to chess. My actual research activities mainly concern the application of fuzzy logics for the modeling of human-like ”thinking” methods, the learning from examples, the construction of intelligent tutoring systems, the parallelization of inference mechanisms, systems of diagnosis and configuration. In cooperation with colleagues from directions of mechanical engineering and medicine, I have been supervising the construction of several expert systems. Four times I received the Scientific Award of the Chemnitz University of Technology.
