Algorithms

Numerous algorithmic problems arise in Bioinformatics over and above [alignment], [evolutionary] trees etc..
 
The longest biased interval (LBI) problem is to find long intervals in a sequence that are of biological interest because they have significantly biased base-composition.
 
Approximate palindromes in DNA may code for miRNAs or have other biological functions.
 
Some "classic" Computer Science algorithms and data structures are also useful in Bioinformatics, for example,
