Looking at Full Looking Ahead

Haralick and Elliott's full looking ahead algorithm [4] was presented in the same article as forward checking, but is not as commonly used. We give experimental results which indicate that on some types of constraint satisfaction problems, full looking ahead outperforms forward checking. We also present three new looking ahead algorithms, all variations on full looking ahead, which were designe...

Looking at Globalization of English in the Context of Internationalism

The present study is an attempt to provide a current synopsis of World Englishes within globalized communities, as well as theoretical and applied feasibility of global linguistic features of English as an International Language (EIL). To do so, first, three main reactions against the spread of English by scholars around the world are discussed. Then, the possibility of describing and teaching ...

Look-Ahead Value Ordering for Constraint Satisfaction Problems

Looking ahead during search is often useful when solving constraint satisfaction problems. Previous studies have shown that looking ahead helps by causing dead-ends to occur earlier in the search, and by providing information that is useful for dynamic variable ordering. In this paper, we show that another bene t of looking ahead is a useful domain value ordering heuristic, which we call look-a...

No more "Partial" and "Full Looking Ahead"

Looking ahead is a commonly used search technique in constraint satisfaction. In this paper, we examine the future role of two long established lookahead algorithms, Partial Looking Ahead (PLA) and Full Looking Ahead (FLA). We prove that PLA is inferior to Directional Arcconsistency Lookahead in that the latter will prune at least as much as the former for no more computation in each problem re...
