Solve rate

Solved runs out of all runs for each agent version, with a 95% Wilson interval. Runs cut short by the machine (a killed process, the LLM server unreachable, the engine timing out) are left out.

Within noise: a difference this size could easily be chance with 4 and 4 runs. Fisher's exact test, two-sided, p = 1.0.

Tokens and time

Medians per run. Tokens come from RubyLLM's usage records; tokens per second is completion tokens over the run's wall time.

Every run

One dot per run, green solved, red stuck and grey interrupted, larger for more rounds; a hollow dot has no checks recorded. Hover or tap a dot for its top errors, and open it for the question's page.

Why checks fail

Each version's failed checks, as shares of the whole, by the hint in Question::HINTS their error matches first, or by the error's class when no hint matches. A check that repeats the error before it, in a streak of 3 or more, counts as a repeated failing move.

Most frequent errors

1. 11undefined method '…' for an instance of Physics::PhysicalObjectNoMethodError: undefined method 'time_taken' for an instance of Physics::PhysicalObject; time_taken is a quantity of Velocity, through UniformCircularMotion, not a method: reach it from a motion, as <motion>.time_taken
2. 9undefined local variable or method '…' for an instance of Physics::SolvingNameError: undefined local variable or method 'stone_motion' for an instance of Physics::Solving
3. 3no equation determines the … from what is knownRuntimeError: no equation determines the time taken of braking from what is known
4. 2ArgumentErrorArgumentError: two_forces_at_right_angles gives the force on body by pusher1 during pushed twice: 8 N and 8 N
5. 2is a word Ruby already usesArgumentError: round is a word Ruby already uses: call it something else
6. 1ArgumentErrorArgumentError: car_braking_to_rest gives the velocity of car at end of braking from ground twice: 0 m/s and 0 m/s
