HomPINNs: homotopy physics-informed neural networks for solving the inverse problems of nonlinear differential equations with multiple solutions [PDF]
J Comput Phys, 2023 Due to the complex behavior arising from non-uniqueness, symmetry, and bifurcations in the solution space, solving inverse problems of nonlinear differential equations (DEs) with multiple solutions is a challenging task.

Inverse design of structural color: finding multiple solutions via conditional generative adversarial networks [PDF]
Nanophotonics, 2022 The “one-to-many” problem is a typical challenge that faced by many machine learning aided inverse nanophotonics designs where one target optical response can be achieved by many solutions (designs).

Extending greedy feature selection algorithms to multiple solutions [PDF]
Data Min Knowl Discov, 2021 Most feature selection methods identify only a single solution. This is acceptable for predictive purposes, but is not sufficient for knowledge discovery if multiple solutions exist.

Multiple solutions for a Schrödinger–Bopp–Podolsky system with positive potentials [PDF]
Mathematische Nachrichten, 2020 In this paper, we prove existence of solutions for a Schrödinger–Bopp–Podolsky system under positive potentials. We use the Ljusternick–Schnirelmann and Morse Theories to get multiple solutions with a priori given “interaction energy.”

Computing multiple solutions of topology optimization problems [PDF]
SIAM Journal on Scientific Computing, 2020 Topology optimization problems often support multiple local minima due to a lack of convexity. Typically, gradient-based techniques combined with continuation in model parameters are used to promote convergence to more optimal solutions; however, these ...
