— A Genetic Algorithm is invoked to search out the wave operator leading to the determination of a few eigenvalues and eigenvectors of a specially designed real symmetric matrix (Durand matrix) that simulates a Hamiltonian supporting bound states coupled to continuum. The performance is compared with that of a standard iterative method for different(More)
BACKGROUND Erythropoietin, originally recognized for its role in erythropoiesis, has been shown to improve neurological outcome after stroke. Low-dose methotrexate is effective against certain inflammatory diseases, such as severe psoriasis and rheumatoid arthritis as well as Crohn's disease. Immunosuppressive effect of methotrexate also reduces the(More)
The growth of evolutionary computing (EC) methods in the exploration of complex potential energy landscapes of atomic and molecular clusters, as well as crystals over the last decade or so is reviewed. The trend of growth indicates that pure as well as hybrid evolutionary computing techniques in conjunction of DFT has been emerging as a powerful tool,(More)
