Abstract

The embodiments of the invention include a computer-readable medium having computer-executable components comprising at least one agent having at least one sensor component, having a goal or change method component, and at least one behavior component. The at least one sensor component generates at least one event based at least in part on at least one generated value from the goal or change method component. The at least one behavior component determines whether to activate a thread of execution based at least in part on the at least one generated event from the at least one sensor component. The system complex execution threads can be generated by any operator on agents level, events level, sensors level and behaviors level.

9. The computer-readable medium of claim 1, wherein the at least one behavior component generates a status event upon the activation of a thread of execution, the status event being receivable by at least one other behavior component.

10. The computer-readable medium of claim 1, wherein the at least one behavior component generates a status event upon the completion of a thread of execution, the status event being receivable by at least one other behavior component.

11. The computer-readable medium of claim 1, wherein the at least one behavior component determines whether to activate a thread of execution based on an independent triggering condition.

12.

16. The computer-readable medium of claim 11, wherein the independent triggering condition is based on the local perception of the at least one behavior component.

17. The computer-readable medium of claim 14, wherein the at least one behavior component activates a thread of execution for an active independent triggering condition before the independent triggering condition becomes active again.

18. The computer-readable medium of claim 1, wherein the at least one behavior and sensor components are defined at least one keyword, wherein the at least one keyword indicates at least one of a particular agent, at least one behavior or sensor and a particular event for activating an independent triggering condition.
