However, the work proved to be tedious and time consuming because of the numerous trial-and-error measurements involved.
On the basis of numerous trial-and-error studies published in the literature, there is a clear consensus on the importance of selecting the appropriate catalyst substrate combination.
To design and refine an algorithm, numerous trial-and-error runs are often performed in order to choose a suitable search operator and the parameters.
The compensator design procedure usually requires numerous trial and errors.
For FnBPA type biofilms, after numerous trial and error steps using a panel of protein-denaturing chemicals, sublethal dose, 0.06 %, of ethanol was found to be the best in disintegrating the proteinacious matrix of FnBPA type biofilms when is mixed with applied phages [data not shown]; however, this dose was of no effect on biofilms or phages when ethanol was used alone.
This guiding process avoids numerous iterations of blind trial-and-error attempts at removing features from the dataset, and quickly finds, in most datasets, very reduced subsets of features.
But there's some trial-and-error involved, and if you have numerous components, the process will likely take at least ten minutes.
Relationships, too, involved painful trial-and-error.
"The process is more trial-and-error, like chess.
Until then, it's basically just trial-and-error.
