To bluff, or not to bluff? Modern-day game theory techniques sheds light on legendary military bluffs

TechAndComputer (May 23, 2011) — Economist Christopher Cotton from the University of Miami (UM), uses game theory to explore two of the most famous military bluffs in history. The findings are published in the current issue of the Journal of Peace Research.

The study is one of the first to use game theory to assess the Chinese military legends of Li Guang and his 100 horsemen (144 BC), and Zhuge Liang and the Empty City (228 AD). The stories appear in modern day translations of Sun Tzu's fundamental book on military strategy "The Art of War" to explain what is meant by deception.

Computer vision: Music video by C-Mon & Kypski used for data collection

  • PDF
TechAndComputer (May 17, 2011) — Researchers at New York University's Courant Institute of Mathematical Sciences have adopted an innovative data collection method for their latest work in the area of computer vision -- a music video created by the Dutch progressive-electro band C-Mon & Kypski. Individual frames from the band's recent video for its song "More is Less" served as a unique visual database for the Courant researchers' work to develop computer vision...

Next generation gamers: Computer games aid recovery from stroke

  • PDF
TechAndComputer (May 16, 2011) — Computer games are not just for kids. New research published in Journal of NeuroEngineering and Rehabilitation, a BioMed Central open access journal, shows that computer games can speed up and improve a patient's recovery from paralysis after a stroke.

It is often difficult for stroke victims to recover hand and arm movement, and 80-90% of sufferers still have problems six months later. Scientists in America...
