We have applied a genetic algorithm (GA) to solve the Steiner Minimal Tree problem in graphs. In this a simple bit string representation is used, where a 1 or 0 corresponds to whether or not a node is included in the solution tree. The standard genetic operators-selection, crossover and mutation-are applied to both random and seeded initial populations of representations. Various parameters within the algorithm have to be set and we discuss how and why we have selected the values used. A standard set of graph problems used extensively in the comparison of Steiner tree algorithms has been solved using our resulting algorithm. We report our results (which are encouragingly good) and draw conclusions the proposed algorithm has several advantages. One advantage is that, it guarantees convergence to an optimal solution with probability one. And another advantage is that, not only the resultant solutions all are feasible, the solution quality is also much higher than that obtained by the other methods (immensely, in almost every case in our simulations, the algorithm can find the optimal solution of the problem).
