CREATED: 200810200322 Title: Algorithm for exploring the space of gene tree/species tree reconciliation

  • LCA: V(G) -> V(S) ** maps a gene u of G onto the species tree S ** most parsimonious LCA reconciliation problem
  • General reconciliation: V(G) -> V(S) ** leaf of G -> leaf of S ** internal node -> LCA or edge above LCA ** descendant relation is preserved
  • 4 Problems ** counting number of reconciliation using DP, O(|G| |S|) time and space ** generating a reconciliation uniformly at random ** operators for exploring the space, upward/download NMC (nearest mapping change) ** exhaustively explore space of reconciliations using operators
