Stopping rules and estimation for recapture debugging with unequal failure rates. (English) Zbl 0770.62069

Summary: A theoretical optimal stopping rule based on the minimization of the testing cost and expected penalty due to the unremoved bugs is derived without the equal failure rate assumption under T. K. Nayak’s [Biometrika 75, No. 1, 113-120 (1988; Zbl 0635.62102)] recapture debugging procedure. Two adaptive stopping rules suitable for practical use are constructed and tested by simulation. The estimation of the number of undetected bugs is also considered via remaining failure rate estimation.
