Substructure (engineering) The substructure of a building transfers the load of the building to the ground and isolates it horizontally from the ground. This includes foundations and basement retaining walls. [1] It is differentiated from the superstructure. It safeguards the building against the forces of wind, uplift, soil pressure etc. It ...
Substructure (mathematics) In mathematical logic, an (induced) substructure or (induced) subalgebra is a structure whose domain is a subset of that of a bigger structure, and whose functions and relations are restricted to the substructure's domain. Some examples of subalgebras are subgroups, submonoids, subrings, subfields, subalgebras of ...
In Marxist theory, society consists of two parts: the base (or substructure) and superstructure. The base refers to the mode of production which includes the forces and relations of production (e.g. employer–employee work conditions, the technical division of labour, and property relations) into which people enter to produce the necessities and amenities of life. The superstructure refers to ...

Definition. A slightly more formal definition of optimal substructure can be given. Let a "problem" be a collection of "alternatives", and let each alternative have an associated cost, c (a). The task is to find a set of alternatives that minimizes c (a).
The most obvious way to define a graph is a structure with a signature consisting of a single binary relation symbol The vertices of the graph form the domain of the structure, and for two vertices and means that and are connected by an edge. In this encoding, the notion of induced substructure is more restrictive than the notion of subgraph.
Dynamic Substructuring (DS) is an engineering tool used to model and analyse the dynamics of mechanical systems by means of its components or substructures. Using the dynamic substructuring approach one is able to analyse the dynamic behaviour of substructures separately and to later on calculate the assembled dynamics using coupling procedures.
Elementary equivalence. In model theory, a branch of mathematical logic, two structures M and N of the same signature σ are called elementarily equivalent if they satisfy the same first-order σ -sentences. If N is a substructure of M, one often needs a stronger condition. In this case N is called an elementary substructure of M if every first ...
