Learning regimeādependent governing equations: A symbolic decision tree approach
AIChE Journal, EarlyView.Abstract Many chemical engineering systems are governed by mechanisms that switch across operating regimes, making the dataādriven discovery of regimeādependent governing equations essential for predictive modeling, optimization, and control. We propose symbolic decision trees for the dataādriven discovery of regimeādependent governing equations.

On Multisymplecticity of Partitioned RungeāKutta Methods [PDF]
SIAM Journal on Scientific Computing, 2008 Previously, it has been shown that discretizing a multi-Hamiltonian PDE in space and time with partitioned Runge-Kutta methods gives rise to a system of equations that formally satisfy a discrete multisymplectic conservation law. However, these previous studies use the same partitioning of the variables into two parts in both space and time. This gives
