experimentwhile

Experimentwhile is a descriptive term used in programming and experimental software to denote a pattern that combines an iterative loop with experimental decision logic. It refers to a loop that continues not merely by a fixed condition but by ongoing assessment of experimental outcomes, allowing the loop to adapt or terminate as results emerge. The term is not a standardized language construct; rather it describes a practice found in workflows that involve data collection, parameter exploration, or instrument control.

Key characteristics of the experimentwhile pattern include dynamic stopping criteria, integration with measurement or control tasks, and built-in data logging. The loop typically performs an action such as taking a measurement, updating a model or parameters, analyzing results, and then deciding whether to continue based on predefined criteria (e.g., achieving a target metric, reaching a resource limit, or hitting a safety bound). This approach supports iterative experimentation and adaptive control within a single procedural flow.

Typical use and form involve a loop governed by a shouldContinue condition, with steps to collect data, process results, and adjust parameters as needed. A simple pseudocode illustration might be:

while shouldContinue():

measurement = takeMeasurement()

result = analyze(measurement)

log(result)

updateParametersIfNeeded(result)

Applications span scientific experiments, real-time data collection, and automated parameter search or optimization tasks. Considerations include ensuring termination guarantees for safety, maintaining reproducible logging, and managing error handling in instrument communication. Related ideas include adaptive experimentation, Bayesian optimization, and loop-based control patterns.
