| Abstract: | This paper proposes a method by which flatness objective functions can be verified to be the function with a single valley by geometric analysis and by means of a computer. Hence, problems which are difficult to solve by pure mathematical method were solved. The method gives the theoretical basis on which flatness objective functions can be correctly computed with optimization principle, it also provides the similar method for verifying the single valley character of objective functions for roundness and cylindricity. |
