Nurse Scheduler V4.0

Fujitsu Chugoku Systems Ltd. and Fujitsu Ltd. announced that they had developed Nurse Scheduler V4.0 with Prof. Kamei's lab of Ritsumeikan University, and both companies put it on the market on 10/21/05. See Japanese press release in detail.

They started to sell Nurse Scheduler V1 and V2 in 1993 and 1996, respectively. Competitive GA was applied to the Nurse Scheduler V3 in 2001, and Cooperative GA is applied to the Nurse Scheduler V4, this time. Thanks to new algorithm, V4 became 4 times faster and 10 times more precise than previous versions, they said.

As of March, 2005, their shedulers have been used at 220 hospitals.

I am a newbie in GA and is currently working on Time-tabling.
I googled "difference between competitive and cooperative Genetic Algorithm" but couldn't find something that explains me in a simple language with example.

Please help.
