Optimizing the length of checking sequences

R.M. Hierons, H. Ural
2006 IEEE transactions on computers  
We show how a set A may be chosen so that it minimizes the sum of the lengths of the sequences to be combined.  ...  An optimization algorithm is used in order to produce the shortest such checking sequence that can be generated on the basis of the given A and E c .  ...  For the 1000 other experiments with a given FSM M we recorded the mean checking sequence length, the maximum checking sequence length, and the minimum checking sequence length.  ...
