Network Search Algorithms with Modifiable Heuristics,s In a recent study, L. Mero suggested a method for run-time modification of heuristic estimate of nodes. This method of modifiable heuristics can in general reduce the total number of node expansions. It is shown in this paper, with counter examples, that Mero’s algorithm (B′) is not as good as cla

In the absence of any knowledge, a depth-first iterative-deepening algorithm is asymptotically optimal in time and space among minimal-cost exp

Backtrack-Free and Backtrack-Bounded Search,ese relate the structure of the problem to the structure of the search sequence. Particular attention is paid to tree-structured constraint satisfaction problems. Problem complexity is shown to have a bound exponential in the size of the largest biconnected component of the problem’s constraint grap

Network-Based Heuristics for Constraint-Satisfaction Problems,. While some CSPs are hard, those that are easy can often be mapped into sparse networks of constraints which, in the extreme case, are trees. This paper identifies classes of problems that lend themselves to easy solutions, and develops algorithms that solve these problems optimally. The paper then

Comparison of the Minimax and Product Back-Up Rules in a Variety of Games,e-hole kalah, othello, and Ballard’s incremental game. In three-hole kalah, the product rule plays better than a minimax search to the same depth. This is a remarkable result, since it is the first widely known game in which product has been found to yield better play than minimax. Furthermore, the
