Initialize the planner.

Parameters:

  • executor (CrowExecutor) – the executor.

  • state (CrowState) – the initial state.

  • goal_expr (str | ValueOutputExpression) – the goal expression.

  • simulation_interface (CrowSimulationControllerInterface | None) – the simulation interface.

  • enable_reordering (bool) – whether to enable reordering.

  • max_search_depth (int) – the maximum search depth.

  • max_beam_size (int) – the maximum beam size.

  • is_goal_ordered (bool) – whether the goal is ordered.

  • is_goal_serializable (bool) – whether the goal is serializable.

  • is_goal_refinement_compressible (bool) – whether the goal refinement is compressible.

  • enable_csp (bool) – whether to enable the CSP solver.

  • max_csp_trials (int) – the maximum number of CSP trials.

  • max_global_csp_trials (int) – the maximum number of global CSP trials.

  • max_csp_branching_factor (int) – the maximum CSP branching factor.

  • use_generator_manager (bool) – whether to use the generator manager.

  • store_generator_manager_history (bool) – whether to store the generator manager history.

  • include_effect_appliers (bool) – whether to include the effect appliers in the search result. The effect appliers are of type CrowEffectApplier.

  • include_dependency_trace (bool) – whether to include the dependency graph in the search result.

  • verbose (bool) – whether to output verbose information.
