Three questions, six designs

Every arm answers the same three questions. Identical cells are printed again, word for word. The stacked sameness is the one-step-change argument, not a shortcut.

Full sentences. Numbers match the chips. The same chip number shares one note.

  1. 1

    A · What do I ask next?

    Arm A asks whatever is still blank on a fixed checklist. It asks all of it at once.

  2. 2

    A · When do I stop?

    Arm A stops when the checklist is full.

  3. 3

    A · What may I say?

    Arm A always takes ranks 1 and 2. “None” only changes the wording.

  4. 4

    B · What do I ask next?

    Arm B asks the one question that splits the most diseases.

  5. 5

    B · C1 · C2 · C3 · When do I stop?

    B, C1, C2 and C3 stop when no remaining answer could change the advice. The spec wrote “Same as B” on C1, C2 and C3. The sentence is repeated in each cell.

  6. 6

    B · C1 · C2 · What may I say?

    B, C1 and C2 may say one disease, an honest tie, or send to the veterinarian. The spec wrote “Same as B” on C1 and C2. The sentence is repeated in each cell.

  7. 7

    C1 · What do I ask next?

    Arm C1 asks the one question that would change what the Farm Operator does. Flag on this row: this setting is currently off.

  8. 8

    C2 · C3 · What do I ask next?

    This is C1 plus expected split from possible answers and saved first-turn work. This was measured worse. The spec wrote “Same as C2” on C3. C2’s sentence is repeated. Alarm marks C2 only.

  9. 9

    C3 · What may I say?

    C3 may say one disease, an honest tie, or send to the veterinarian. The consistency note is for the record only.

  10. 10

    D · What do I ask next?

    Arm D asks the sign the most listed diseases say they have.

  11. 11

    D · When do I stop?

    Arm D stops on a count that never reached zero.

  12. 12

    D · What may I say?

    Arm D says the whole ranked list.

How to read the grid

Repeat is the point. Four copies of B’s stop rule stacked in one column is the one-step-change argument. A left rail marks inheritance. The words stay fully readable. Cyan is where that arm placed its bet. Red is a named defect.

Where each arm bet

  • A — the scoring contest
  • B, C1, C2 — what to ask next
  • C3 — a note that never guides a decision
  • D — a count that never hit zero

The four alarms

  • A always takes ranks 1 and 2
  • C2 added cleverness and got worse
  • D’s door never opened
  • D then said the whole ranked list
