 Global approximation

A design function which is representative of the entire design space.

 Global Optimization

The mathematical procedure for finding the global optimum in the design space. E.g. Genetic Algorithm, Particle Swarm, etc.

 Global variable

A variable of which the scope spans across all the design disciplines or solvers. Used in the MDO context.

 Gradient vector

A vector consisting of the derivatives of a function f in terms of a number of variables x1 to xn. s = [df /dxi]. See Design Sensitivity.
