Run and improve a solve

Generate a result, configure advanced solving, save progress, or continue from history.

Generate with basic controls

With Advanced controls off, the workflow bar contains Setup, Generate Groups, and Results.

Select Generate Groups to validate the scenario, run the recommended Auto plan, save the result, and open it. While the run is active, the button shows Generating… and progress. Cancelling from this basic control stops and discards that run.

If validation fails, the notification is titled Scenario needs changes and includes Review groups, Review people, or Review constraints. Correct the first reported issue before generating again.

Open the advanced Solver workspace

Open the product menu, then Editor preferences, and enable Advanced controls. The Solver workspace adds Run, four Plan sections, Orchestration, Runs, and Settings JSON.

On Run, the Recipe control offers:

Auto recommended — expands to concrete Scope, Starting Point, Search, and Effort settings;
Custom — keeps those settings editable.

Changing one Plan section switches that section to Custom. This recipe choice is separate from the Auto, Extreme, and Ultra Extreme orchestration modes.

Configure the plan

Plan section	Auto behavior	Custom use
Scope	All sessions are editable	Select the sessions that may change
Starting Point	Build a new starting schedule	Choose a saved result as a warm start or change construction policy
Search	Local improvement with recommended controls	Choose Local improvement or Annealing improvement and edit search parameters
Effort	Complexity-derived runtime	Choose Fixed total runtime, seed, stopping controls, and Parallel lanes

A partial Scope preserves unselected sessions as completed history only when Starting Point uses a saved result. The Scope page shows Partial scope needs a saved starting result until that is configured. Selected future sessions are optimized jointly.

For Parallel Auto, every lane receives the configured full budget and the best result is retained. Set Parallel lanes to 1 for a single lane. The maximum depends on the browser’s worker capacity.

Choose orchestration

Mode	Behavior
Auto	Executes the configured plan once.
Extreme	Runs Auto, then continues score-polishing batches until cancelled.
Ultra Extreme	Runs a multi-stage expert search, can save resumable state, and has stricter capability limits.

Select Use Auto, Use Extreme, or Use Ultra Extreme on the corresponding page. Extreme is open-ended, not a larger fixed runtime. Ultra Extreme has stricter capability checks and does not support partial session Scope.

Run, save, and cancel

The advanced Run page is enabled after Available Solvers finishes loading. If it shows Available Solvers Unavailable, generation remains disabled; reload once and use Troubleshoot scenarios and solves if the catalog still fails.

Select Run with Manual Settings to start the displayed plan.

While running:

Save Best So Far saves the latest valid result and continues solving.
Cancel Solver opens cancellation choices.

For ordinary runs, cancellation offers:

Back — continue the run;
Discard Run — stop without saving the current snapshot;
Save Result Snapshot — save the latest valid snapshot and stop.

Ultra Extreme also offers Pause & Save Run, which saves a resumable Ultra run. Save Result Snapshot saves only a result, not resumable orchestration state.

A save can fail when no valid best-so-far schedule exists or browser storage cannot persist it. GroupMixer reports that failure instead of claiming a result was saved.

Continue from completed history

Open a saved result and select Continue from history.

Enter Completed earliest sessions from 1 through one less than the total session count.
Confirm which early sessions become immutable and which remaining sessions will be optimized together.
With basic controls, select Generate remaining sessions; the run starts immediately.
With Advanced controls, select Continue to solver; review the prepared Scope and saved-result Starting Point, then run.

The action requires a complete saved result whose people, groups, attendance, capacities, and session count still match the current scenario. Auto, Local improvement, and Annealing improvement are supported. Ultra Extreme and unsupported families imported through Settings JSON are rejected.

Apply Settings JSON

Settings JSON is under Advanced. It accepts a raw solver settings object or supported settings, default_solver, or input.solver wrappers. The object must include solver_type, stop_conditions, and solver_params. Quote integer seeds that exceed JavaScript’s safe integer range.

Select Apply settings JSON to replace the scenario’s solver settings; this is not a merge. Reset to current discards an unapplied draft. Use this surface for exact reproduction or diagnostics, then review the plan before running.

After completion, use Understand results.
