Uncertainty quantification and optimization becomes particularly challenging when either the nature of the system or cost limitations prevent the deployment of a large number of sensors for data collection. We propose a novel trajectory design approach for the optimal experimental design (OED) of contiguous data acquisition based on a network-flow formulation. In contrast to conventional control strategies, we discretize the spatial domain into a set of network nodes and identify the optimal path between nodes to minimize uncertainty. This approach allows for a more thorough exploration of the design space than what multi-start local optimizations can do. The network-flow approach we propose translates into a challenging discrete optimization problem, whose objective is expensive to evaluate, highly nonlinear, and can be non-smooth. Moreover, the objective function needs to be evaluated over the entire path instead of being summed edge-by-edge. With an increasing number of edges, the number of possible paths rapidly increases and the combinatorial problem becomes intractable. We showcase a branch-and-bound algorithm we developed, which leverages tailored bounds and constraints to tackle the optimization at a tractable computational cost.<\/p>\n<div class=\"tribe-events-single-event-description tribe-events-content\">\n<p>&nbsp;<\/p>\n<p><b>Bio: <\/b>Marco Mangano is a postdoc in the Argonne MCS division. He holds a PhD from the University of Michigan (US, 2023), an MSc from TU Delft (NL, 2019), and a BSc from University of Padua (IT, 2014), all of them in Aerospace Engineering. His previous\u00a0research focused on multidisciplinary design optimization (MDO) for wind and hydrokinetic turbines using high-fidelity simulations in the loop. He is currently developing novel optimization algorithms for digital twins, with particular focus on data assimilation and optimal experimental design problems.
