Planning Experiments: Resolving Interactions between Two Planning Spaces

Learning from experimentation allows a system to acquire planning domain knowledge by correcting its knowledge when an action execution fails. Experiments are designed and planned to bring the world to a state where a hypothesis e.g., that an operator is missing a precondition can be tested. When planning an experiment, the planner must take into account the interactions between the execution of the main plan and the execution of the experiment plans, since after the experiment it must continue to carry on its main task. In order for planners to work in such environments where they can be given several tasks, they must take into account the interactions between them. A usual assumption in current planning systems is that they are given a single task or set of goals to achieve. However, a plan that may seem adequate for a task in isolation may make other tasks harder or even impossible to achieve. Di erent tasks may compete for resources, execute irreversible actions that make other ta...
