Watch: Interpret an exact geometric network domain, optionally construct a candidate, and enter the globally minimal length or cost in the declared unit. The shell keeps the complete question visible, reserves the canonical reply band, and reveals proof on the same task objects.

Misread: Child action: Interpret an exact geometric network domain, optionally construct a candidate, and enter the globally minimal length or cost in the declared unit.

Task formats

Connected grid exact-cover partition and count

Connected grid exact-cover partition and count asks the player to partition every active grid cell into equal-size connected regions, then enter the derived region count.

ActionPartition every active grid cell into equal-size connected regions, then enter the derived region count.

Selection

Fresh independent work can move toward Core, Transfer, or Challenge routes; help use or confusion keeps support visible.

Help

Hints keep attention on the visible structure; reveals show the path without counting as independent evidence.

Presentation

Presentation can reduce reading and interaction load without changing the selected skill. Practice focus can bias compatible work without breaking prerequisites or story fit.

Story fit

  • Episodes whose mathematical action is construct or inspect exact code-owned grid and network structures, then derive a validated count or optimum.
