quantum mechanics, the Hamiltonian is a first-class constraint on physical states. We also have an independent constraint for each point in space. Although...

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

similar to that of first- and second-class constraints. These divisions are independent: both first- and second-class constraints can be either primary...

classical gauge theories. i.e. those that can be described with first class constraints. The more general formalism is described using the Batalin–Vilkovisky...

{\displaystyle e} . Therefore, the constraint is now a secondary constraint that is still a first class constraint, reflecting the invariance of the action...

The Town class consisted of 10 light cruisers built for the Royal Navy during the 1930s. The Towns were designed within the constraints of the London Naval...

Constraint logic programming is a form of constraint programming, in which logic programming is extended to include concepts from constraint satisfaction...

of the first submarine of the class, Yury Dolgorukiy (Юрий Долгорукий), was scheduled for 2002 but was delayed because of budget constraints. The vessel...
