Networks are trained by\npenalising the equation residual, boundary and initial\nconditions, and misfit to observations, following Raissi,\nPerdikaris and Karniadakis (2019)\n. Everything runs in native R on\ntop of 'torch', with no 'Python' dependency, and ordinary\ndifferential equation models written as 'deSolve'-style\nderivative functions can be used directly.",
