In computer science, a charging argument is used to compare the output of an optimization algorithm to an optimal solution. It is typically used to show that an algorithm produces optimal results by proving the existence of a particular injective function. For profit maximization problems, the function can be any one-to-one mapping from elements of an optimal solution to elements of the algorithm's output. For cost minimization problems, the function can be any one-to-one mapping from elements of the algorithm's output to elements of an optimal solution.

Famous quotes containing the words charging and/or argument:
“Faster than fairies, faster than witches,
Bridges and houses, hedges and ditches;
And charging along like troops in a battle,
All through the meadows the horses and cattle;”
—Robert Louis Stevenson (18501894)
“Our argument ... will result, not upon logic by itselfthough without logic we should never have got to this pointbut upon the fortunate contingent fact that people who would take this logically possible view, after they had really imagined themselves in the other mans position, are extremely rare.”
—Richard M. Hare (b. 1919)
