02. Benchmark: Math Reasoning

Intro

This benchmark tests WAA on deterministic math tasks where the difficulty comes from workflow synthesis rather than ambiguous answers. The useful question is whether WAA can consistently assemble and reuse the right workflow for a small but varied math task set.

Benchmark Cases

The benchmark cases fall into four small groups:

  • Direct arithmetic: tasks where one tool or one obvious two-step workflow should be enough.
  • Compositional arithmetic: tasks that require combining several primitive tools in a fixed order.
  • Symbolic calculus and trigonometry: tasks that depend on derivative or trig identities.
  • Stress cases: tasks where the planner has to reconstruct a familiar formula from the available tool set.

One small caveat is worth calling out. task_8 (sin(x)^2 + cos(x)^2) has the same expected output for every input because the identity always evaluates to 1. That makes it useful as an identity-recognition case, but weak as a pure composition test: a degenerate workflow that returns a constant can still pass numerically.

Results

The results below come from the benchmark run documented in this note. Each task was run five times. The most useful metrics here are how many reruns completed, how much retry pressure each task needed, and how large the resulting workflows were.

The workflow artifacts used in this note do not currently persist wall-clock runtime, so this section uses saved retry counts instead of average duration.

Conclusion

In this benchmark, all 15 tasks were run 5 times. 14 tasks completed in all 5 runs. task_8 completed in 4 of 5 runs and remains the main exception in this set.

task_8 is also defined in a way that lets the system in its current form exploit the test. Because all expected outputs are identical, the system can fill in the final answer directly instead of building the intended trig workflow. The numeric output is not necessarily wrong, but it is not the behavior this task was meant to reward.

This benchmark shows that, for this system, workflow composition is easier to trust when more than one test case is provided and the expected outputs vary across those cases. When every expected output is identical, a shortcut or overfitted answer may pass.
