Mixed-Initiative Constraint-Based Planning
Mixed initiative constraint based planning is a complex planning system that
requires extensive interactions between a human planner and a computer planner
which works as an optimal scheduler to maximize on one or more dimensions while
maintaining given relationships (i.e., constraints) between activities. The
primary goal of mixed initiative planning is to maximize the potential of human
planners and computer planners by ensuring each do the tasks to which they are
best suited. Human planners are experts at formulating goals and setting constraints,
and computer planners can perform computationally intensive tasks to create
plans which meet those goals and satisfy those constraints. When adequate solutions
cannot be found, human planners must reason about constraints in order to solve
problems, and relax constraints to satisfice. In order for this process to be
successful, humans must be able to convey the right information to the computer,
and humans must be able to understand the decisions that the computer has made.
