Abstract

Various embodiments enable an agent that utilizes a first, as-needed canonical rule set in a first execution environment to be moved to a second execution environment where the agent utilizes a second, as-needed canonical rule set.

Claims

1. A computer-implemented method, comprising:

receiving an encoded agent in an execution environment, the encoded agent being received from a different execution environment, the encoded agent including an as-needed canonical rule set;

decoding the encoded agent to create a decoded agent;

compiling the as-needed canonical rule set;

searching to locate a rule engine;

creating a rule engine in response to a failure to locate the rule engine;

supplying a created or a found rule engine with a compiled as-needed canonical rule set; and

requesting a working memory from the rule engine.

2. The computer-implemented method of claim 1, wherein creating the rule engine comprises creating the rule engine using the decoded agent.

3. The computer-implemented method of claim 1, wherein receiving the encoded agent comprises receiving the encoded agent using an agent manager residing in the execution environment that receives the encoded agent.

4. An article of manufacture including a computer-readable medium having instructions stored thereon that, responsive to execution by a computing device, cause the computing device to perform operations comprising:

receiving an encoded agent in an execution environment, the encoded agent being received from a different execution environment, the encoded agent including an as-needed canonical rule set;

decoding the encoded agent to create a decoded agent;

compiling the as-needed canonical rule set;

searching to locate a rule engine;

creating a rule engine in response to a failure to locate the rule engine;

supplying a created or found rule engine with a compiled as-needed canonical rule set; and

requesting a working memory from the rule engine.

5. The article of manufacture of claim 4, wherein creating the rule engine comprises creating the rule engine by the decoded agent.

6. The article of manufacture of claim 4, wherein receiving the encoded agent comprises receiving the encoded agent by an agent manager residing in the execution environment that receives the encoded agent.

7. An article of manufacture including a computer-readable medium having instructions stored thereon that, responsive to execution by a computing device, cause the computing device to perform operations comprising:

moving an agent that utilizes a first as-needed canonical rule set in a first execution environment embodied on a first device to a second execution environment embodied on a second device, where the agent utilizes a second as-needed canonical rule set, by at least;

discarding a rule in the first execution environment that will not be needed in the second execution environment;

retrieving an additional rule that will be needed in the second execution environment; and

sending the agent including the additional rule from the first execution environment to the second execution environment.

8. The article of manufacture of claim 7, wherein a discarded rule is specific to a context of the first execution environment.

9. The article of manufacture of claim 7, wherein a retrieved additional rule is specific to a context of the second execution environment.

10. The article of manufacture of claim 7, wherein the operations further comprise discarding the first as-needed canonical rule set in the first execution environment.

11. A system comprising:

a tangible computer-readable storage medium;

an agent, embodied on the tangible computer-readable storage medium and configured to utilize a first as-needed canonical rule set in a first execution environment embodied on a first device, the agent further being configured to, responsive to a request by an application to move the agent to a second execution environment embodied on a second device, utilize a second as-needed canonical rule set by at least;

discarding a rule in the first execution environment that will not be needed in the second execution environment;

retrieving an additional rule that will be needed in the second execution environment; and

sending the agent including the additional rule from the first execution environment to the second execution environment.

12. The system as recited in claim 11, wherein the second as-needed canonical rule set is supplied in the request to move the agent.

13. The system as recited in claim 11, wherein the agent is further configured to retrieve the second as-needed canonical rule set from a rule repository based on goals of the agent and destination execution environment.

14. A computer-implemented method, comprising:

moving an agent that utilizes a first as-needed canonical rule set in a first execution environment embodied on a first device to a second execution environment embodied on a second device by at least;

requesting a second as-needed canonical rule set based on a goal and an execution environment of the agent;

requesting movement of the agent from the first execution environment to the second execution environment;

encoding the agent with the second as-needed canonical rule set; and

sending an encoded agent with the second as-needed canonical rule set from the first execution environment to the second execution environment, wherein the sending causes the encoded agent to be decoded in the second execution environment.

15. The computer-implemented method as recited in claim 14, wherein the requesting the second as-needed canonical rule set is performed by an application requesting the second as-needed canonical rule set from a rule repository.

16. A computer-implemented method as recited in claim 15, wherein the rule repository is in a third execution environment.

17. The computer-implemented method as recited in claim 14, further comprising supplying the second as-needed canonical rule set as part of the request for movement of the agent.

18. The computer-implemented method as recited in claim 14, wherein the request includes a location of a rule repository that can supply the second as-needed canonical rule set.

19. The computer-implemented method as recited in claim 18, wherein the agent is configured to cause the second as-needed canonical rule set to be fetched from the rule repository when the agent arrives in the second execution environment.

20. An article of manufacture including a computer-readable medium having instructions stored thereon that, responsive to execution by a computing device, cause the computing device to perform operations comprising:

moving an agent that utilizes a first as-needed canonical rule set in a first execution environment to a second execution environment where the agent utilizes a second as-needed canonical rule set, by at least;

discarding the first as-needed canonical rule set;

retrieving the second as-needed canonical rule set;

encoding the agent including the second as-needed canonical rule set;

sending an encoded agent with the second as-needed canonical rule set to the second execution environment; and

destructing an original version of the agent in the first execution environment.

21. The article of manufacture of claim 20, wherein a discarded rule is specific to a context of the first execution environment.

22. The article of manufacture of claim 20, wherein the second as-needed canonical rule set is retrieved from a move request.

23. The article of manufacture of claim 20, further comprising compiling the second as-needed canonical rule set.

24. A computer-implemented method, comprising:

moving an agent that utilizes a first as-needed canonical rule set in a first execution environment to a second execution environment where the agent utilizes a second as-needed canonical rule set, by at least;

discarding the first as-needed canonical rule set;

retrieving the second as-needed canonical rule set;

encoding the agent including the second as-needed canonical rule set;

sending an encoded agent with the second as-needed canonical rule set to the second execution environment; and

destructing an original version of the agent in the first execution environment.

25. The computer-implemented method as recited in claim 24, further comprising retrieving the second as-needed canonical rule set from a rule repository given goals of the agent and destination execution environment.

26. The computer-implemented method as recited in claim 24, further comprising compiling the second as-needed canonical rule set and supplying a compiled as-needed canonical rule set to a rule engine for execution.

27. The computer-implemented method as recited in claim 24, further comprising supplying a location of a rule repository that can supply the second as-needed canonical rule set as part of a request for movement of the agent.
