When a plan specifies all the actions you need to perform but specifies the order of the steps only when necessary, it’s called a partial-order plan.
A Partial-Order Plan is a representation of a plan in artificial intelligence where the actions are partially ordered based on their dependencies and constraints. In a partial-order plan, not all actions are strictly ordered in a linear sequence; instead, some actions can be executed concurrently or in a flexible order as long as certain conditions or constraints are satisfied. This flexibility allows for more efficient planning in domains where actions can be parallelized or where the exact order of execution is not crucial. In summary, a partial-order plan captures both the sequential and concurrent aspects of planning, providing a more flexible and adaptable framework for solving complex problems.
