2025-12-10 Fractional dominating set (Generalization of dominating sets using fractional weights) In graph theory, a fractional dominating set is a generalization of the dominating set concept that allows vertices to be assigned fractional weights between 0 and 1, rather than binary membership. This relaxation transforms the domination problem into a linear programming problem, often yielding more precise bounds and enabling polynomial-time computation. B BagLuke (1235)
2025-09-17 False confidence theorem (Statistical principle for robust inference) The false confidence theorem suggests that an analyst should not be willing to assign a high degree of belief to an assertion on the basis of low quality data. High belief here would be unjustified, the confidence placed in the assertion could be said to be false. Start LackingConfidence (16)
2025-12-04 Game theory on networks (Study of strategic interactions on networks) Game theory on networks is a field that studies strategy in competing interest interactions among rational or adaptive players that are affected by the topology of networks.

2026-07-09 Political expressive behaviour (Political action taken to express identity) Political expressive behaviour is political action taken mainly to express who a person is, their identity, values, or group loyalties, rather than to bring about a particular result. Scholars in public choice, political science, and political psychology use the idea to explain forms of political participation, primary voting, that are hard to explain if one assumes people act only to change outcomes, since the probability that one voter will affect the political outcome is negligible. C Wicko Peddlefoot (667)
2026-07-23 Optimal auditing (Study of strategies for verifying reports) Optimal auditing is the study, in economics and game theory, of how a principal should verify reports made by strategic agents when verification is costly.
