Subset
A subset, also called a set inclusion, is a set all of whose members also belong to another set B, written A ⊆ B; a proper subset leaves at least one member out.
Subset sum problem
The subset sum problem asks whether some subset of a set of integers sums exactly to a target. It was proved NP-complete in Richard Karp's 1972 paper.
Subshift of finite type
A subshift of finite type, also called a Markov shift, is a set of infinite sequences avoiding a finite list of forbidden words, central to symbolic dynamics.
Subsidence
Subsidence, also called land or ground subsidence, is the sinking of the Earth's surface caused by groundwater pumping, mining, or soil drainage; over 80 percent of known US subsidence stems from groundwater use.
Subsidence analysis
Subsidence analysis is a geology method that reconstructs a basin's downward movement through time, using backstripping to remove sediment loading and isolate tectonic subsidence, whose curve shape diagnoses basin type.
Subsidiarity (Catholicism)
Subsidiarity in Catholicism: the principle of Catholic social teaching that higher authorities must not supplant individuals, families, local communities, and intermediary bodies, but aid and coordinate them for the common good; formulated in Quadragesimo anno (1931).

Subsonic ammunition
Subsonic ammunition, also called subsonic rounds, is firearm ammunition loaded to a muzzle velocity below the speed of sound, eliminating the supersonic crack and used chiefly with sound suppressors.
Subspace clustering
Subspace clustering is an unsupervised machine learning method that groups data points assumed to lie near a union of low-dimensional subspaces, used in motion segmentation and face clustering.
