Method Detail

execute

public java.lang.Object execute(Environment environment)

This method returns the Solution Object among its inputs, whose IntUpperBound has minimal intValue, provided that it is at least as low as the Shared objects intValue. Otherwise, it returns null, indicating that none of its input Solution objects is the current best.

Specified by:

execute in class Task

Parameters:

environment - The environment's Shared Object defines the currently best known minimal intValue associated with a Solution. It is possible, though unlikely, that the Task's input Solutions contain a better one than the TaskServer knows about, as reflected in the Environment's Shared object's intValue. If this occurs, a side-effect of the execute method is to update the Environment's Shared object accordingly.

Returns:

the Solution Object among its inputs, whose IntUpperBound has minimal intValue, provided that it is at least as low as the Shared objects intValue. Otherwise, it returns null, indicating that none of its input Solution objects is the current best.

executeOnServer

public boolean executeOnServer(Environment environment)

This task executes on the task server.

Overrides:

executeOnServer in class Task

Parameters:

environment - Session environment (ignored).

Returns:

true: This task executes on the task server.
