Solution Techniques
Early CGE models were often solved by a program custom-written for that particular model. Models were expensive to construct, and sometimes appeared as a 'black box' to outsiders.
Today most CGE models are formulated and solved using one of the GEMPACK or GAMS software systems. Other systems such as AMPL or MATLAB are also used. Use of such systems has lowered the cost of entry to CGE modelling; allowed model simulations to be independently replicated; and increased the transparency of the models.

Famous quotes containing the words solution and/or techniques:
“The Settlement ... is an experimental effort to aid in the solution of the social and industrial problems which are engendered by the modern conditions of life in a great city. It insists that these problems are not confined to any one portion of the city. It is an attempt to relieve, at the same time, the overaccumulation at one end of society and the destitution at the other ...”

“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about “purposeful play” and “cognitive learning skills.””
