, 2017 In the Shortest Superstring problem (SS) one has to find a shortest string s containing given strings s_1,...,s_n as substrings. The problem is NP-hard, so a natural question is that of its approximability.

A Deep Learning Approach Using Optimized LSTM for Anomaly‐Based Network Intrusion Detection
Journal of Engineering, Volume 2026, Issue 1, 2026.With the exponential rise in cyber threats, anomaly‐based network intrusion detection systems (NIDSs) have become critical for maintaining robust cybersecurity. This article proposes an optimized long short‐term memory (LSTM) deep learning (DL) model specifically designed to detect anomalies in network traffic.

Topological Stability of Kinetic $k$-Centers [PDF]
, 2018 We study the $k$-center problem in a kinetic setting: given a set of continuously moving points $P$ in the plane, determine a set of $k$ (moving) disks that cover $P$ at every time step, such that the disks are as small as possible at any point in time ...

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 736-761, December 2025.ABSTRACT Accurate prediction of fatigue life under multiaxial loading conditions remains challenging due to complex stress–strain interactions. In this study, we integrate machine‐learning (ML) regression with variance‐based sensitivity analysis (SA) to predict multiaxial fatigue life in CuZn37 brass and to identify the dominant mechanical factors ...

A Match in Time Saves Nine: Deterministic Online Matching With Delays
, 2017 We consider the problem of online Min-cost Perfect Matching with Delays (MPMD) introduced by Emek et al. (STOC 2016). In this problem, an even number of requests appear in a metric space at different times and the goal of an online algorithm is to match ...

Exact Covers via Determinants [PDF]
, 2010 Given a k-uniform hypergraph on n vertices, partitioned in k equal parts such that every hyperedge includes one vertex from each part, the k-dimensional matching problem asks whether there is a disjoint collection of the hyperedges which covers all ...

Ecosphere, Volume 16, Issue 7, July 2025.Abstract Birds and their habitats are threatened with extinction around the world. Regional assessments of the “State of Birds” are a vital means to prioritize data‐driven conservation action by informing national and global policy. Such evaluations have traditionally relied on data derived from extensive, long‐term, standardized surveys that require ...

Optimality program in segment and string graphs
, 2018 Planar graphs are known to allow subexponential algorithms running in time $2^{O(\sqrt n)}$ or $2^{O(\sqrt n \log n)}$ for most of the paradigmatic problems, while the brute-force time $2^{\Theta(n)}$ is very likely to be asymptotically best on general ...
