Certainty estimation of numerical results obtained by several methods of problem solution
In the present paper the methods of estimating the results obtained by numerical modeling are suggested. The situation is considered when there are series of numerical methods of the same problem solution. It is necessary to estimate the accuracy of every method and its certainty if there is no divergence of results. As certainty numerical characteristic, making use of the probability that real error does not exceed the numerical error is suggested.
