Practically Error‐Free Junctions Enable Solving Large Instances of Exact Cover Problems Using Network‐Based Biocomputation

open access: yesSmall, Volume 22, Issue 59, 22 October 2026.
Scaling nanofluidic channel geometries to sub‐200 nm is demonstrated to suppress junction guiding errors in network‐based biocomputing. The resulting increase in path fidelity enables experimental solution of Exact Cover instances with more than 33 million possible solutions, establishing a new benchmark for network‐based biocomputing.

Algorithms for four variants of the exact satisfiability problem

open access: yes, 2004
We present four polynomial space and exponential time algorithms for variants of the EXACT SATISFIABILITY problem. First, an O(1.1120n) (where n is the number of variables) time algorithm for the NP-complete decision problem of EXACT 3-SATISFIABILITY ...

Lyapunov‐Function‐Based Stability Region Estimation in Transient Stability Assessment of Inverter‐Based Resources: A Review

open access: yesHigh Voltage, Volume 11, Issue 5, Page 1611-1634, October 2026.
ABSTRACT Electric power systems are undergoing a fundamental transition from synchronous generator (SG)‐dominated systems to inverter‐based resource (IBR)‐dominated systems. Lyapunov‐ and energy‐function‐based direct methods provide an effective way to estimate the stability region, also known as the region of attraction (ROA), and have become a ...

SMT-COMP: Satisfiability Modulo Theories Competition

open access: yes, 2005
Decision procedures for checking satisfiability of logical formulas are crucial for many verification applications (e.g., [2, 6, 3]). Of particular recent interest are solvers for Satisfiability Modulo Theories (SMT).

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

open access: yesAdvanced Electronic Materials, Volume 12, Issue 17, 7 September 2026.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

open access: yesJournal of Graph Theory, Volume 113, Issue 1, Page 143-164, September 2026.
ABSTRACT Given a graph G, we say that an orientation D of G is a KT orientation if, for all u , v ∈ V ( D ), there is at most one directed path (in any direction) between u and v. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as counterexamples to various ...

Search Algorithms for Satisfiability Problems in Combinational Switching Circuits

open access: yes, 1995
A number of tasks in computer-aided analysis of combinational circuits, including test pattern generation, timing analysis, delay fault testing and logic verification, can be viewed as particular formulations of the satisfiability problem (SAT).

Learning From Satisfiability [PDF]

open access: yes, 1997
A formalisation of concept-learning in logic is presented under the name learning from satisfiability. It generalizes learning from entailment as employed in inductive logic programming and learning from interpretations as used in attribute-value ...

Faster than classical quantum algorithm for dense formulas of exact satisfiability and occupation problems

open access: yesNew Journal of Physics, 2016
We present an exact quantum algorithm for solving the Exact Satisfiability problem, which belongs to the important NP-complete complexity class. The algorithm is based on an intuitive approach that can be divided into two parts: the first step consists ...
