In view of the coefficient matrix being full or dense, the Gaussian elimination method is unfeasible because of its heavy computational and storage load.
In the last years, the meta-heuristics proved to be one of the most effective methods to tackle difficult optimization problems, providing an alternative in cases where exact methods would be unfeasible.
We also give a heuristic method based on structural metrics for locating possible linchpins as their exact identification is unfeasible in practice, and presently there are no better ways than the brute-force method.
We omitted SOMA's statistical test (also for Valouev's likelihood method, where it is not enabled by default), because it is unfeasible for large datasets [ 19], and applied only its uniqueness test (F-test).
Therefore, it is unfeasible to compare directly the performance of our proposed method with them.
It is usually determined by pipette or hydrometer methods, but analysis requires a preparation with chemical reagents, which can take hours and hence is unfeasible for large number of samples.
However, there are situations where the application of this method is not possible, for example in unforeseen cases and emergencies, where collecting preoperative data is unfeasible.
A group of dogs receiving ketoprofen was used as control due to ethical reasons, considering that the use of a placebo group is unfeasible in a study whose main objective is to find the best method to provide pain relief.
Due to the scope of our analyses, employing experimental methods to determine the rate of false predictions in all or even a representative sample of species is unfeasible.
