To illustrate these points, we present a video comparison of different isosurfacing methods for mesh optimization. Starting from a sphere initialization, we optimize the shapes towards the ground truth mesh (bottom-right) using a set of isosurfacing methods. DC and NDC lackgradient differentiation, ...

A common feature of many gradient-based methods employed in production optimization is that these gradient approximation techniques have been utilized within the SD framework. The SD framework utilizes first-order information about the objective function to direct the search in the direction of descent ...
Among the three types RADO methods, the latter two are more efficient than the MCS-based one. However, for the design optimization with a large number of design parameters, model-based optimization is time-consuming and sometimes low-fidelity. Moreover, sensitivity-based UQ is inaccurate when th...

In the first talk, we provide a tutorial overview of most of the main approaches currently used for carrying out simulation optimization, which includes stochastic approximation, response surface methodology, and sample average approximation, as well as some random search methods. Simple examples will ...
