In Section 4 , we study the classical properties of the generalized expenditure function and we deduce that the generalized Hicksian demand is locally Lipschitz continuous.. The

In this paper, we use a genetic algorithm (GA) based optimization to generate a suitable configuration of the PLL-TRNG, such that it is secure and reaches high output bit rate..

The method is based on an adaptive strategy in the UQ loop to reduce the number of samples in the stochastic space for those designs that are not interesting for optimization

Our design of a Multi-Objective Gradient Descent (MOGD) solver uses carefully-crafted loss functions to guide gradient descent to find the minimum of a target objective while
