ingap-cdg
codon-based de Bruijn graph algorithm for gene construction
Currently, most gene prediction methods detect coding sequences (CDSs) from transcriptome assembly when lacking of closely related reference genomes. However, these methods are of limited application due to highly fragmented transcripts and extensive assembly errors, which may lead to redundant or false CDS predictions. Here we present a novel algorithm, inGAP-CDG, for effective construction of full-length and non-redundant CDSs from unassembled transcriptomes. inGAP-CDG achieves... -

The min cost is a program which is going to find the minimum cost or path of any given numbers. if you have a certain set of numbers this program is going to calculate the optimized cost for that set. Similarly, the program can perform Dijkstra's algorithm which is an algorithm for finding the shortest paths between nodes in a graph by simply insert the node distance in the input file and output the shortest path in output file. The program was written in C++ using a main algorithm of a heap...

SplitMEM
Graphical pan-genome analysis with suffix skips
With the rise of improved sequencing technologies, genomics is expanding from a single reference per species paradigm into a more comprehensive pan-genome approach with multiple individuals represented and analyzed together. Here we introduce a novel O(n log n) time and space algorithm called splitMEM, that directly constructs the compressed de Bruijn graph for a pan-genome of total length n. To achieve this time complexity, we augment the suffix tree with suffix skips, a new construct... -

We consider a problem of finding maximum weight subgraphs (MWS) that satisfy hard constraints in a weighted graph. The constraints specify the graph nodes that must belong to the solution as well as mutual exclusions of graph nodes, i.e., pairs of nodes that cannot belong to the same solution. Our main contribution is a novel inference approach for solving this problem in a sequential monte carlo (SMC) sampling framework. Usually in an SMC framework there is a natural ordering of the states...

MolSig
The Stereo Signature Molecular Descriptor
An algorithm to compute molecular graph descriptors considering the stereochemistry of the molecular structure, based on our previously introduced signature molecular descriptor. The algorithm can generate two types of descriptors, one which is compliant with the Cahn-Ingold-Prelog priority rules, and a faster one based on our previous definition of a directed acyclic graph that isaugmented to a chiral molecular graph. -

Approximate Subgraph Matching Algorithm
Approximate Subgraph Matching Algorithm for Dependency Graphs
The subgraph matching problem (subgraph isomorphism) is NP-complete. Previously, we designed an exact subgraph matching (ESM) algorithm for dependency graphs using a backtracking approach (http://esmalgorithm.sourceforge.net). We further designed an approximate subgraph matching (ASM) algorithm that is capable of detecting approximate subgraph matching based on a subgraph distance. Assume that the graph G and the subgraph Gs have m and n vertices, and km and kn edges respectively... -

ProGraphMSA
Graph-based multiple sequence alignment
ProGraphMSA is a state-of-the-art multiple sequence alignment tool which produces phylogenetically sensible gap patterns while maintaining robustness by allowing alternative splicings and errors in the branching pattern of the guide tree. This is achieved by incorporating a graph-based sequence representation as in POA and combines it with the advantages of the phylogeny-aware algorithm in Prank. Further, we account for variations in the substitution pattern by using estimated amino acid... -

Discriminative subgraph mining by learning from search history
LTS (Learning to Search) is an implementation of an algorithm described in "LTS: Discriminative Subgraph Mining by Learning from Search History" in Data Engineering (ICDE), IEEE 27th International Conference, pages 207-218, 2011. The purpose of LTS is to find discriminative subgraphs, which are smaller graphs that are embedded in larger graphs that all share a certain trait. A discriminative subgraph can help to characterize a complex graph and can be used to classify new graphs with unknown... -

Griso is a graph isomorphism testing utility written in C++. It is based on my own POLYNOMIAL-TIME (in this point the salt of the project) algorithm. See Griso's sample input/output on http://funkybee.narod.ru/graphs.htm page. Edit (2012-10-24): seems so far it works for *regular graphs only* and should be tested on such graphs. Edit (2012-10-25): see two counterexamples in README.txt. But yet if Griso's verdict is "NON-isomorphic" it's 100% correct, so you can still make use of it. PS...

Intelligent Water Drops Algorithm
Solving optimization problems by the Intelligent Water Drops algorithm
This project deals with the Intelligent Water Drops algorithm or the IWD algorithm. The IWD algorithm is a population & nature-inspired combinatorial optimization algorithm. It tries to imitate the behavior that natural water drops conduct in river beds where they create complex paths that seem optimistic considering the environment, obstacles, and the surrounding terrain. One way to use the IWD algorithm is to map our optimization problem into a graph over which Intelligent Water Drops (IWDs...
