The phrase "almost optimal for" is correct and usable in written English.
It can be used when discussing a solution or method that is very close to the best possible outcome but not quite there.
Example: "The algorithm we developed is almost optimal for solving this specific problem, achieving a high level of efficiency."
Alternatives: "nearly optimal for" or "close to optimal for".
In practice, such an estimator design is either assumed to be almost optimal for window- and stability-time errors or a cumbersome simulation-based optimization is conducted to achieve optimality in this respect.
Furthermore, it is almost optimal for a class of moderately soft potentials, that is for a moderate singularity.
It is possible to present that this is asymptotically almost optimal for many signals, which have been corrupted by additive white Gaussian noise.
Therefore, the optimal parameters computed for the Bus video would be almost optimal for the other four video sequences generated by the same encoding parameters.
These optima were often quite broad, suggesting that investment in repair remains almost optimal for small changes in environmental conditions.
We give an almost optimal solution for diameter 2 and bounds for large diameters.
EDS explored about 40 000 AFs to find an almost optimal AF for this problem, using the most general pattern " ".
It is important to note that the ℓ1-minimization algorithm produces almost optimal results for signals that are not k-sparse.
However, in practice, we are able to efficiently offer almost optimal solutions for small-scale problems of several covering entities.
In his seminal paper, after stating the Harnack estimates, Moser proved almost optimal estimates for the parabolic kernel by using the so called 'Harnack chain' method.
They analyzed different algorithms, and indicated that a vector (or multi-dimensional) bin packing algorithm [9, 10, 11] is able to reach almost optimal result for the problem.
