Senior Staff Scientist

Mr. Tim Hays has 30+ years of software product development experience and pioneered programs available on floppy-disks, embedded ROM systems, CDs and DVDs. He has worked with Cinemaware, Sony, Sega, Virgin, Shiny, Interplay, and Electronic Arts and has completed over 70 published software products. Focusing on multiplayer Artificial Intelligence (AI), physical-model/physics engines, and real-time 3D graphics simulations, Mr. Hays has created titles in many entertainment genres such as Fox Studios The X-Files, Sony Gameday Football, Terry Bradshaw Football '97, Sony ESPN Baseball Tonight, Electronic Arts NHL Hockey '93 to '98, Virgin Games' Muhammad Ali Boxing, Shiny's Messiah, Shiny's R/C Stunt Copter, and a WWI flight simulator titled "Wings" which was the best selling game of all time on the Amiga computers (Cinemaware in 1990), MacAttack (first 3D game out on the Macintosh computers) and Harrier Strike Mission I & II (best sellers on early MACs), on consoles such as the Sony Playstation, Nintendo, Sega Genesis, DreamCast & Saturn, Bally Arcade, Atari series computers, Amiga and Windows PCs. His knowledge of combining highly optimized assembly language with C/C++ code allowed him to create products with some of the fastest graphics (both 2D and 3D) available on several platforms.

Mr. Hays is a senior member of the IEEE. He has created several business training (CBT) courses & three MBA degree courses, functioning as a producer and designer. Mr. Hays has extensive knowledge of video codecs/video compression, video editing, SFX, 3D graphics, Photoshop, streaming video, Flash-animation, and has used his knowledge and programming skills to create products for several companies using his own multimedia engine with high-quality SD & Hi-Definition video for CD, DVD and Web delivery.

Mr. Hays joined Natural Selection, Inc. in 2003 to work on the application of automated evolved pattern recognition tables and object neural networks to improve commercial software products. He was the lead programmer on Evolutionary Checkers Starring Blondie24 (Digenetics, 2001) and Chess with an Attitude! (Digenetics, 2003), and was instrumental in transferring results from the Phase I SBIR project into this chess game, allowing it to play at the level of a human master. Mr. Hays has two patents awarded, both relating to the design and display of intelligent characters in games. Mr. Hays has studied at seven colleges in the areas of Computer Science, VR Design, Physics, Chemistry & Biology, Instrumental Music and Electronics and his hobbies and study interests include Bioscience, Quantum Physics, Anthropology, Photography, Hi-Def Video Editing and Effects.
