## Contents

# Concepts and categories

Big O notation: http://rob-bell.net/2009/06/a-beginners-guide-to-big-o-notation/

## Dynamic programming

See http://en.wikipedia.org/wiki/Dynamic_programming

Examples of dynamic programming algorithms:

- Needleman-Wunschm algorithm
- Smith-Waterman algorithm
- Sankoff algorithm
- Viterbi algorithm

# Algorithms

Identifying K-mer clumps:

## Numerical optimization

Simplex algorithm:

## Sequence alignment

Needleman–Wunsch algorithm:

Dynamic programming algorithm to perform global sequence alignment. Also referred to as the "optimal matching algorithm". Introduced in 1970.

http://en.wikipedia.org/wiki/Needleman%E2%80%93Wunsch_algorithm

In general parlance, a Needleman-Wunsch type algorithm refers to a global alignment algorithm that takes quadratic time for a linear or affine gap penalty.

Smith Waterman algorithm:

http://en.wikipedia.org/wiki/Smith%E2%80%93Waterman_algorithm

Dynamic programming algorithm for local sequence alignment. Introduced in 1981. Can be considered a variation of the Needleman-Wunsch algorithm. Guaranteed to find the optimal local alignment with respect to the scoring system used.

See also http://seqanswers.com/forums/showthread.php?t=25305 for a discussion on implementing SW.

## Other

Burrows-Wheeler transform:

Also called "block-sorting compression". String transformation algorithm used in data compression. Transforms a character string by permuting the order of the character, to increase the number of character repeats.

Used by the sequence alignment program BWA.

Viterbi algorithm:

From Wikipedia: "The Viterbi algorithm is a dynamic programming algorithm for finding the most likely sequence of hidden states – called the Viterbi path – that results in a sequence of observed events, especially in the context of Markov information sources and hidden Markov models."

Baum-Welch algorithm (Baum-Welch expectation maximization):

http://en.wikipedia.org/wiki/Baum%E2%80%93Welch_algorithm

Invented by Leonard E. Baum and Lloyd R. Welch, the Baum-Welch algorithm is used to estimate the unknown parameters of a Hidden Markov Model (HMM).
