An ant colony algorithm for the sequential testing problem under precedence constraints.
We consider the problem of minimum cost sequential
testing of a series (parallel) system under precedence
constraints that can be modeled as a nonlinear integer program.
We develop and implement an ant colony algorithm for the
problem. We demonstrate the performance of this algorithm
for special type of instances for which the optimal solutions
can be found in polynomial time. In addition, we compare the
performance of the algorithm with a special branch and bound
algorithm for general instances. The ant colony algorithm is
shown to be particularly effective for larger instances of the
problem
