A method for determining the number and location of instrumentation probes to be inserted into a program is disclosed. The method advantageously inserts the minimum number of probes that are required to obtain execution coverage for every node in the program's control-flow graph. In addition, the method requires only one bit to store each probe and does not require the assignment of weights to arcs or nodes of the control-flow graph. In the illustrative embodiment, the nodes of a control-flow graph are partitioned into non-empty sets, where each non-empty set corresponds to a super nested block of the program.
