A trivial upper bound on the time complexity of CSP search algorithms is O * ( d n ), where n and d are the number of variables and the maximal domain size of the underlying CSP, respectively. In this paper we
imply that IDA* is asymptotically optimal in time and space over allheuristic search algorithmsthat find optimal solutions on a tree. Additional benefits of IDA* are that it is much easier to implement, and often runs faster than A*, since it does not incur the overhead of managing the Open...

Two representative search algorithms in this category are SA and TS, which have been discussed in Chapters 5 and 6. Either accepting solutions worse than the current solution (or best-so-far solution) from time to time or searching particular solutions makes it possible for LS to escape from ...

Figure 8 shows the power, FEs and runtime used to detect eight high-order EINMEs using five intelligent search algorithms, and the results show that the power of MTHSA-DHEI exceeds that of the other four algorithms in all EINMEs except for MP-HS-DHSI, which has the same power value as...
However, the retrieval speeds of algorithms for searching similar WSIs often scale with the repository size, which limits their clinical and research potential. Here we show that self-supervised deep learning can be leveraged to search for and retrieve WSIs at speeds that are independent of ...
algorithms using many realizations with random initial positions, and analyze the influence of the stochastic drift on the search success. In comparison to conventional search methods, the proposed algorithm leads to an order of magnitude improvement in success rate over the time period of the actual...

There is some indication that in a standard ILS algorithm, using this perturbation mechanism — despite its relatively high time-complexity — can result in slightly better performance than using simple double-bridge perturbation [Codenotti et al., 1996]. However, state-of-the-art ILS algorithms ...
