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. 3undefined 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. 3no equation determines the … from what is knownRuntimeError: no equation determines the time taken of braking from what is known
3. 1gives … but never says where in what it asksArgumentError: a_whirled_stone gives turns but never says where in what it asks
4. 1ArgumentErrorArgumentError: car_braking_to_rest gives the velocity of car at end of braking from ground twice: 0 m/s and 0 m/s
5. 1ArgumentErrorArgumentError: car_braking_to_rest takes distance as (position of car at end of braking - position of car at start of braking), a formula of quantities; don't work it out, name the quantity and the engine finds it: that formula is what the laws give for car.displacement(during: braking).magnitude, use car.displacement(during: braking).magnitude for distance
6. 1ArgumentErrorArgumentError: two_forces_at_right_angles takes acceleration as (net force on body during pushed / mass of body), a formula of quantities; don't work it out, name the quantity and the engine finds it. No single law in using: gives this formula of body.net_force(during: pushed).magnitude and body.mass; name what is asked and the engine chains the laws it needs
7. 1undefined local variable or method '…' for an instance of Physics::SolvingNameError: undefined local variable or method 'resultant_force' for an instance of Physics::Solving
8. 1gives nothing called …ArgumentError: two_forces_at_right_angles gives nothing called resultant_force
9. 1NoMethodErrorNoMethodError: undefined method 'x_component' for an instance of Physics::Whole; x_component is a quantity of Vectors, through NewtonsSecondLaw, not a method: it belongs to no object
10. 1which none of its laws name/give to anythingNameError: two_forces_at_right_angles chooses a root of #<struct Physics::Pointing size=#<Physics::Whole:0x0000780573890490 @name=#<struct Physics::Instance quantity=:force, variable=:F, owner=:body, qualifiers={by: :pusher1, during: :pushed}, labels={body: "", pushed: ""}>, @written=#<struct Physics::Instance quantity=:force, variable=:F, owner=:body, qualifiers={by: :pusher1, during: :pushed}, labels={body: "", pushed: ""}>>>, which none of its laws name
