... output object. Doing so would result in an O(f log² n) term in the overall search complexity, where f is the output size. In this paper, we develop several techniques to handle the first two problems by making strong use of the Q-heap technique. In particular, we show that, under the RAM model used ...

... the binary rule increases with L/N. Although the binary rule reduces search signi cantly (the peak mean number of branches goes down from approximately 6 to 1.31), it does not appear to be very e ective in the variable region. This suggests that the binary rule will not eliminate the constraint gap ...

Basic Principles of Hill-climbing Due to their combinatorial explosion nature, many real life constraint optimisation problems are hard to solve using complete methods such as branch & bound [Hall 1971, Reingold et. al. 1977]. One way to contain the combinatorial ex ...

When a node with unexplored child is reached (nv = 0) a new node is created for one of the unexplored children. The process then starts ag ...

Binary search algorithm

In computer science, a binary search or half-interval search algorithm finds the position of a target value within a sorted array. The binary search algorithm can be classified as a dichotomic divide-and-conquer search algorithm and executes in logarithmic time.
