“Some problems are so challenging to solve that even the most advanced computers need weeks, not seconds, to process them. Now a team of researchers at Georgia Institute of Technology and University of Notre Dame has created a new computing system that aims to tackle one of computing’s hardest problems in a fraction of the time. “We wanted to find a way to solve a problem without using the normal binary representations that have been the backbone of computing for decades,” said Arijit Raychowdhury, an associate professor in Georgia Tech’s School of Electrical and Computer Engineering. Their new system employs a network of electronic oscillators to solve graph coloring tasks – a type of problem that tends to choke modern computers. Details of the study were published April 19 in the journal Scientific Reports. The research was conducted with support from the National Science Foundation, the Office of Naval Research, the Semiconductor Research Corporation and the Center for Low Energy Systems Technology.”
