In mathematics, constraint counting is counting the number of constraints in order to compare it with the number of variables, parameters, etc. that are...

Constraint satisfaction problems (CSPs) are mathematical questions defined as a set of objects whose state must satisfy a number of constraints or limitations...

with the single constraint. Counting the number of variables leads to width n {\displaystyle n} , while counting the number of constraints leads to width...

solutions we might optimistically expect, we can appeal to Einstein's constraint counting method. A typical conclusion from this style of argument is that...

check constraint is a type of integrity constraint in SQL which specifies a requirement that must be met by each row in a database table. The constraint must...

A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties: 203 ...

principle of counting constraints: if we have a number N of parameters to adjust (i.e. we have N degrees of freedom), and a constraint means we have...
