Combinatorial design theory is the part of combinatorial mathematics that deals with the existence, construction and properties of systems of finite sets...

Combinatorics is well known for the breadth of the problems it tackles. Combinatorial problems arise in many areas of pure mathematics, notably in algebra...

Combinatorial chemistry comprises chemical synthetic methods that make it possible to prepare a large number (tens to thousands or even millions) of compounds...

In mathematics, a combinatorial class is a countable set of mathematical objects, together with a size function mapping each object to a non-negative...

In proving results in combinatorics several useful combinatorial rules or combinatorial principles are commonly recognized and used. The rule of sum, rule...

Combinatorial optimization is a subfield of mathematical optimization that consists of finding an optimal object from a finite set of objects, where the...

In mathematics, a combinatorial explosion is the rapid growth of the complexity of a problem due to how the combinatorics of the problem is affected by...

A combinatorial auction is a type of smart market in which participants can place bids on combinations of discrete heterogeneous items, or “packages”...
