Autonomous agents are designed to reach goals that were pre-de ned by their operators. An important way to execute tasks and to maximize payo is to share resources and to cooperate...
Java bytecodes can be executed with the following three methods: a Java interpretor running on a particular machine interprets bytecodes; a Just-In-Time (JIT) compiler translates ...
Heterogeneity and uncertainty are two main characteristics of pervasive computing environment and CSCW. CSCW can be viewed as a special case of pervasive computing. Middleware is ...
