The phrase "approximation to the true" is correct and usable in written English.
It can be used in contexts where you are discussing a value, concept, or representation that is close to but not exactly the actual or true value.
Example: "The model provides an approximation to the true behavior of the system under study."
Alternatives: "estimate of the actual" or "near representation of the true".
Nevertheless, it is plausible to believe, at least for well-conserved molecular regions where mutations are reasonably rare and unlikely to have occurred repeatedly at any given variant locus, that the process of approximating small changes with smallest changes could provide a good approximation to the true evolutionary process of the observed set of taxa [ 14].
A piece-wise linear approximation to the true silhouette can then be found by applying dual-contouring techniques.
Given some norm in which accuracy is desired, the optimal test functions render the numerical solution the best approximation to the true solution in that norm.
This is thought to be a desirable property, although only in the case of linear systems is it sufficient for convergence of a consistent approximation to the true solution.
Reddy's third-order theory provides a parabolic distribution of the transverse shear stresses in the thickness direction and represents a close approximation to the true shear strain distribution for a shallow single-layer plate.
The modified differential transform method (MDTM) technique introduces an alternative framework designed to overcome the difficulty of capturing the periodic behavior of the solution, which is characteristic of oscillator equations, and give a good approximation to the true solution in a very large region.
It avoids the use of complex algebra but gives a good approximation to the true definition % voltage unbalance [20].
Meanwhile, the rate of approximation to the true solution by the numerical solution is different for different numerical schemes.
The Keplerian system, amended in the manner of Horrocks to infer mean distances from the periods, is therefore the preferred approximation to the true motions.
Therefore, we have a discrete weighted approximation to the true posterior p(x t |z t ) by using the discrete random measures.
