Geometric programming thermal example
WebThe theory and practice of geometric programming has been stable for a genera-tion, so it is hard to imagine saying anything novel about either. The attractions of geometric programming include its beautiful duality theory and its connections with the arithmetic-geometric mean inequality. The present paper derives new algorithms Webeither because of the relevant geometric, physical or economic laws, or because the log of a posymonomial T i = c i Qm j taij j is a linear function ln c i + Pm j a ij lnt j of the logs, lnt …
