{i+m-1}} $$ However, the average-case performance of the KMP algorithm has been suspected not to be drastically better than that of the naive method [9]: "The Knuth-Morris-Pratt algorithm is not likely to be significantly faster than the brute-force method in most actual applications, ...

Above is the graphical output of the BLASTn algorithm. Each of the matching sequences are shown in blue, indicating their poor alignment score (a score of only “40-50” according to the key; perfect matches are typically red). Each rectangle is a ‘matching’ sequence. Not only do they...
We have chosen to exclude the naive algorithm and all algorithms in the literature based on FFT techniques from our experiments, because, the overhead of such algorithms is quite high resulting in a bad performance. All algorithms have been implemented in Microsoft Visual C++ in Release Mode on...
positions, the modification preserves the correctness of the naive program. This new string matcher performs the same sequence of character comparisons between the pattern and the text as the right-to-left variant of the Horspool variant of the Boyer-Moore algorithm [12]. In addition it perfor...
If your input is short enough, you may consider using some non-efficient algorithm, for example:Backtracking. Implementing and maintaining non-efficient/naive algorithms is usually much easier, and if your input is really short, it won’t hurt performance by very much –but be careful!
If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty...
It would determine the branches to use and build up a RegexProgram which contained branches which were specially optimized for the given string rather than defaulting to a single algorithm based on a few cheesy checks. This would allow all types of node searching logics to be applied ...
This one is pretty unique. It first does a naive pass, then uses a few heuristics to merge any rectangles it can find as merge-worthy. Nice. Joke Algorithm, example by Sergiu Petrila Gridmancer:29 rectanglesin33 statements Eppstein: Nope!
Suppose that you upgrade your application and change the structure of the Person class such that it contains different member variables; perhaps the class records and measures ages with a different data type or algorithm. You would have to rewrite a lot of your API to accommodate this change. ...
