... chart algorithm with full -search (GCF), and generalized chart algorithm with ordered search (GCO). The rules used for the experiments are in the spoken language understanding task, and they are ... ordered search. Although ordered search guarantees that the first solution is the best one, it is not always very ef- ficient. We can think of other search strategies, like...
