    "abstract": "Methods for the computation of invariants and symmetries of nonlinear\nevolution, wave, and lattice equations are presented. The algorithms are based\non dimensional analysis, and can be implemented in any symbolic language, such\nas Mathematica. Invariants and symmetries are shown for several well-known\nequations.\n  Our Mathematica package allows one to automatically compute invariants and\nsymmetries. Applied to systems with parameters, the package determines the\nconditions on these parameters so that a sequence of invariants or symmetries\nexists. The software can thus be used to test the integrability of model\nequations for wave phenomena.",
