All Near Neighbor GraphWithout Searching

Edgar Chávez, Verónica Ludueña, Nora Reyes, Fernando Kasián • Journal of Computer Science and Technology (2018)

Given a collection of n objects equipped with a distance function d(·, ·), the Nearest Neighbor Graph (NNG) consists in finding the nearest neighbor of each object in the collection. Without an index the total cost of NNG is quadratic. Usin...

System 2 Thinking in OpenAI’s o1-Preview Model: Near-Perfect Performance on a Mathematics Exam

Joost C. F. de Winter, Dimitra Dodou, Yke Bauke Eisma • Computers (2024)

The processes underlying human cognition are often divided into System 1, which involves fast, intuitive thinking, and System 2, which involves slow, deliberate reasoning. Previously, large language models were criticized for lacking the de...

Introduction to Mathematical Logic.

Angelo Margaris, Alonzo Church • American Mathematical Monthly (1957)

is sometimes called the foundation of mathematics: the logician studies the kinds of reasoning used in the individual steps of a proof. Alonzo Church was a pioneer in the field of mathematical logic, whose contributions to number theory and...

Robustness of a bisimulation-type faster-than preorder

Katrin Iltgen, Walter Vogler • Electronic Proceedings in Theoretical Computer Science (2009)

TACS is an extension of CCS where upper time bounds for delays can be specified. Luettgen and Vogler defined three variants of bismulation-type faster-than relations and showed that they all three lead to the same preorder, demonstrating th...

An Introduction to Mathematical Logic

Elliott Mendelson • A K Peters/CRC Press eBooks (2005)

Logic, the systematic study of reasoning, is one of the oldest branches of mathematics. For example, the notion of a syllogism was important to the ancient Greeks, and the phrase “Aristotelian logic” is still commonly used. But the flowering...

Existence results and Ulam-Hyers stability for a sequential deformable fractional initial value problem

Leila Slimane, Souad Ayadi, Ozgur Ege, Ahmad Aloqaily et al. • Journal of Inequalities and Applications (2026)

Abstract In this study, we establish existence and Ulam-Hyers results for nonlinear sequential fractional differential equations involving the deformable derivative. We employ the Banach contraction principle and Krasnoselskii’s theorem to ...
