In 1968, Geoffrion [1] proposed a slightly restricted definition of efficiency that eliminates efficient points of a certain anomalous type and lended itself to more satisfactory characterization.
This follows directly on from our previous definition of efficiency: low error and low runtime implies an efficient method, high error and high runtime implies an inefficient method, and a combination of the two, for instance high error but low runtime, clearly lies somewhere between the two.
It relies on a very narrow definition of efficiency: that market prices immediately adjust to all available information.
On its own, a lower cost isn't a valid definition of efficiency: efficiency would entail achieving an equivalent benefit for that lower cost.
Other approaches may be possible and would not substantially alter the operation of the greedy algorithm, while results will be depending on the adopted definition of efficiency ratio.
Although multiple LUE definitions are reported in the literature, we used a definition of efficiency of light use by photosynthetically active "green" vegetation (LUEgreen) based on radiation absorbed by "green" photosynthetically active vegetation on a daily basis.
In this paper, the efficiencies of split-plot design relative to split-block design for experiments of hypothesis testing problems are explored with the definition of efficiency based on the sample size of the experiments.
The highly integrated and synergistic nature of poly-generating high temperature fuel cells, however, precludes a simple definition of efficiency for analysis and comparison of performance to traditional methods.
There are five relations linking them: the power formula (the first law), the definition of efficiency, the definition of the internal entropy source (the second law for the internal system), the definition of the total entropy source (the second law for the total system) and the definition of the cost.
