Webaverage) to find the exact motif, with similar hardware. Approximate algorithms fare little better. For example, a recent paper on finding approximate motifs reports taking 343 seconds to find motifs in a dataset of length 32,260 [23], in contrast we can find exact motifs in similar datasets, and on similar hardware in under 100 seconds. WebFinding Higher Order Motifs Sinha (2002) reviews methods for finding higher order motifs, and groups the approaches based on their general relationship to simple motif finders – find simple motifs and discover patterns made of these – start with simple motifs and build higher order ones – find higher order motifs from scratch (e.g.
