Practice

Complete a sequencing review

Order the workflow for solving a constrained sequence.

Constraint board

Place forced items before testing open positions

  1. RecordWrite each constraint
  2. ForcePlace fixed items and chains
  3. PropagateUpdate remaining positions
  4. TestTry valid alternatives
  5. VerifyCheck every original rule

Translate every precedence, adjacency, window, and exclusion rule into visible placement evidence.

Arrange in the correct order
  1. 1. Verify the finished sequence against every rule
  2. 2. Test remaining possibilities
  3. 3. Propagate chains and adjacency effects
  4. 4. Place fixed and forced items
  5. 5. Translate each sentence into a constraint
