Exploring epidemic control policies using nonlinear programming and mathematical models
Table 4
Comparison of different optimisation algorithms using IPOPT. The optimisation across platforms was performed on the same optimisation model, using the lockdown case scenario as an example (n = 100 runs, dt = 0.5). Hessian nnz denotes the number of non-zero elements of the Lagrangian Hessian matrix. Objective function evaluations (183) and Lagrangian Hessian evaluations (128) were identical across all platforms.
