Algorithm Runtime Estimator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

A zero operations-per-second rate makes the runtime denominator vanish, requiring rejection or producing Infinity in plain JavaScript. The O(n log n) convention is also under-specified because the logarithm base changes the estimate.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "n": 7500000,
    "complexity_class": "O(n)",
    "rate_ops_per_sec": 2500000
  },
  "expected_outputs": {
    "ops": 7500000,
    "runtime_seconds": 3,
    "human_runtime": "3 s"
  },
  "working": "f(n)=n=7,500,000 ops. time=ops/rate=7,500,000 ÷ 2,500,000=3 seconds. 3 seconds=3 s."
}
