The Needleman-Wunsch algorithm finds the optimal global alignment of two sequences by dynamic programming, filling a scoring matrix and tracing back the best path. It is the foundation of bioinformatics — comparing genes, proteins, and genomes. The heatmap shows the accumulated score matrix.

Governing equation

F_{i, j} = max (F_{i - 1, j - 1} + s, F_{i - 1, j} + d, F_{i, j - 1} + d), d = - 2, score = 0

Reading this result: Low similarity: only 0% of columns match (score 0). The optimal alignment leans on -2-penalty gaps and mismatches, so the sequences share little common structure.

About this simulation

The full Sequence Alignment tool models a food web with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
