Constraint

• Biological constraints, factors which make populations resistant to evolutionary change • Carrier's constraint on lung function in long thin animals • Finite domain constraint, in mathematical solution-finding • Integrity constraints in databases • Check constraint • Foreign key constraint • Specific types of mechanical constraints: • First-class constraint and second-class constraint in Hamiltonian mechanics • Primary constraint, secondary constraint, etc. in Hamiltonian mechanics • Holonomic constraints, also called integrable constraints, (depending on time and the coordinates but not on the momenta) • Nonholonomic constraints • Pfaffian constraint • Scleronomic constraint (not depending on time) • Rheonomic constraint (depending on time) == See also ==
