In this paper, a new three-parameter extension of the generalized geometric distribution of [6] is introduced. The new discrete distribution belongs to the resilience parameter family and handles a decreasing, increasing, upside-down and bathtub-shaped hazard rate function. The new distributions can also be considered as discrete analogs of some recent continuous distributions belonging to the ...

We study the multitime distribution in a discrete polynuclear growth model or, equivalently, directed last-passage percolation with geometric weights. A formula for joint function is derived setting. It takes form of multiple contour integral block Fredholm determinant. The asymptotic then computed by taking appropriate KPZ-scaling limit this formula. This expected to be universal models Kardar...

In this paper, the discrete method of eigenvectors of covariance matrix has been used to weight minimization of steel frame structures. Eigenvectors of Covariance Matrix (ECM) algorithm is a robust and iterative method for solving optimization problems and is inspired by the CMA-ES method. Both of these methods use covariance matrix in the optimization process, but the covariance matrix calcula...
