Optimal Control- Please click this link to see the python code and research article at Github It seems I am encountering an "invalid value encountered" warning in your computation for the optimal control problem related to the COVID-19 SIR model. This issue might arise due to numerical instability, division by zero, or invalid operations like taking the logarithm of negative numbers. Here’s a checklist to troubleshoot: Input Parameters: Check your input parameters (initial conditions, control variables, etc.) to ensure they are within valid ranges. Mathematical Expressions: Verify your equations to avoid operations that could lead to NaNs or infinities. Numerical Solver Settings: If you're using solvers like odeint or similar, ensure proper settings for tolerances. Feel free to provide details about the exact error location or the numerical functions used for more specific guidance! Code for Optimal Control Continue reading...
