Approximate

Describing a measure coming close to but not necessarily reaching the exact value. Approximate measures can be inaccurate but are often necessary when more precise information is unavailable.

The relationship between the expectations of the two approximations |Mathematical Expression Omitted~ and |Mathematical Expression Omitted~ is given in (18), which when applied to the point of approximation is stated as:
The subintervals where the approximations are sufficiently accurate are then identified with find for further processing.
There is an interesting "symmetry" between the relative A-norms of the errors and the energy backward errors of the approximations [u.

We prefer to leave its discussions, together with those for crossed dynamic difference approximations, to our forthcoming papers.
In the papers mentioned above, a problem of vector data reduction is solved mostly by polygonal approximation (usually with heuristic methods) or by vector quantization.
Some authors acknowledge that larger n may be needed for some population distributions (Aczel and Sounderpandian (2006)), but even with such disclaimers, these authors give no indication of how much larger n may need to be in order that approximation using the CLT is satisfactory.
Different types of connectivity may be considered: 4-neighbours, 6-neighbours, 8-neighbours, leading to different approximations of the Euler-Poincare characteristic.
The Arrow-Pratt coefficient has direct influence in higher-order pricing approximations.
However, replacing actual analysis or evaluation by approximate model involves its own share of risks and several issues need to be addressed in employing fitness approximations in evolutionary computation (Figure 1).
