Subgraph Isomorphism BY DANIEL HEFNER Definition Applications Medical research Disease gene association Biochemical networks Information analysis Information or event extraction Bioinformatics Protein-protein

  1. Subgraph Isomorphism BY DANIEL HEFNER

  2. Definition

  3. Applications  Medical research  Disease gene association  Biochemical networks  Information analysis  Information or event extraction  Bioinformatics  Protein-protein association

  4. NP Hard  Consider the maximum clique problem.

  5. Strategy  Search for a mapping:  Chose an assignment for each vertex  If at any point a valid assignment cannot be made, return to the previous vertex and chose a different assignment  The answer is found when either a valid mapping is constructed or all valid options are eliminated.

  6. Refined search pattern  ILF(k) – Node degrees  LAD – Node adjacencies
