Investigating Interative Inference Bound Deepening in Top Down .. - Scott Buffett   (Correct)

....the first list again, in hopes of finding a better proof, but we did not want to backtrack any further, since this would cause the goal lists to be reversed. This does not allow for any cuts to control the backtracking, since there is nowhere to put them. To overcome this difficulty, an eclipse [e95] global variable, reverse goals flag, was used as a flag to indicate whether the first list had been solved or not. Initially, the reverse goals flag is set to yes , but if the first goal list is solved, the reverse goals flag is set to no . This instructs the procedure not to reverse the two ....

....tree. It is straight forward to generalize visit look to handle simple program annotations, by which programmers specify when to invoke the stochastic solver and when to rank child branches. 5 Experimental Results In this section we detail a number of preliminary experiments using the ECLiPSe [5] system augmented with a GENET stochastic solver [3] to illustrate the benefits that are possible. The two guiding principles for using a stochastic solver to control search have already been shown to be beneficial. The visit fail procedure is equivalent to an approach of Stuckey and Tam ....
