Performance of cryptanalytic quantum search algorithms is mainly inferred fromquerycomplexity which hides overhead induced by an implementation. To shed light on quantitative complexity analysis removing hidden factors, we provide a framework for estimating time–space complexity, with carefully accounting ...
According to this theorem, a deterministic machine can simulate non-deterministic machines by using a small amount of space.For time complexity, such a simulation seems to require an exponential increase in time. For space complexity, this theorem shows that any non-deterministic Turing machine that...

We show that isomorphism testing ofk-trees is in the class StUSPACE(logn) (strongly unambiguous logspace). This bound follows from a deterministic logspace algorithm that accesses a strongly unambiguous logspace oracle for canonizingk-trees. Further we give a logspace canonization algorithm fork-paths....

In the LP-based distance metrics learning in Section 4.2, the computational complexity of searching the neighboring points with same and different labels using LSH is O(nd), where d is the number of the hash bins in LSH. The computational complexity of the linear programming in Eq. (9) ...
This means that after sufficient time, subject to the complexity of the problem, the solutions are good enough for use, which may not be strictly optimal though. This is a great boon as the exact methods would not even have managed to return a single solution. The sampling-based motion ...
High-speed closest codeword search algorithms for vector quantization One of the most serious problems for vector quantization is the high computational complexity involved in searching for the closest codeword through a code... CH Lee,LH Chen - SIGNAL PROCESSING -AMSTERDAM- 被引量: 0发表: 1995...
Furthermore, considering the complexity of SIN, the security assurance also depends on cross-layer strategies or network functions. Zhou et al. [27] analyzed the relation between threats and services in SIN. They compared the difference in secure routing protocols and anomaly detection methods betwee...
The index may be constructed using any one of the deterministic algorithms. Our techniques also imply the first sub-linear space algorithm for Problem 3. We present the following results. • We can compute S via a deterministic algorithm in O(nτ2lognτ) time using O(n/τ)-words ...
