Greedy motif search
http://www.biopred.net/motivsuche.html WebEeager and Lazy Learning. "Eager" is used in the context of "eager learning". The opposite of "eager learning" is "lazy learning". The terms denote whether the mathematical modelling of the data happens during a separate previous learning phase, or only when the method is applied to new data. For example, polynomial regression is eager, while ...

WebGreedy Motif Search Input: Integers k and t, followed by a collection of strings Dna. Output: A collection of strings BestMotifs resulting from applying GreedyMotifSearch(Dna,k,t). If at any step you find more than one Profile-most probable k-mer in a given string, use the one occurring first.

Earliest Start Time First i.e. select the interval that has the earliest start time. Take a look at the following example that breaks this solution. This solution failed because there could be an interval that starts very early but that is very long.
