trace
fun traceFilePath(runOutputDir: Path, trackingSpec: SolverTrackingSpec, solverSpec: SolverSpec?): Path?(source)
Compute the CSV trace file path inside a specific run directory.
Falls back to a solver-derived stem when SolverTrackingSpec.csvFileName is null. The fallback uses solverSpec.name when present, else the algorithm-kind serial name (e.g. "stochasticHillClimbing"), else "solver".
Returns null when SolverTrackingSpec.enableCsvTrace is false.
