In this paper we present a new method to find simple or multiple roots of functions in a finite interval. In this method using bisection method we can find an interval such that this function is one to one on it, thus we can transform problem of finding roots in this interval into an ordinary differential equation with boundary conditions. By solving this equation using collocation method we ca...

Performance models exist that reliably describe the execution time and efficiency of discrete-event simulations executed in a synchronous iterative fashion. These performance models incorporate the effects of processor heterogeneity, other processor loads due to shared computational resources and application workload imbalance. We extend these models to include the effects of an optimistic tech...

OBJECTIVE A sense of optimism, which derives from the ways individuals explain causes of daily events, has been shown to protect health, whereas pessimism has been linked to poor physical health. We examined prospectively the relationship of an optimistic or pessimistic explanatory style with coronary heart disease incidence in the Veterans Affairs Normative Aging Study, an ongoing cohort of ol...

UCRL This strongly optimistic approach is based on UCRL2 (Jaksch, Ortner, and Auer 2010), which defines a confidence set over each transition/reward distribution, and takes the maximum valid distribution in the confidence set when planning. Specifically, in a finite-horizon setting it allows the L1 norm of the transition distribution to deviate from the MLE by at most √ 14 log(SA`τ`/δ) max(N,1)...
