- rcognita.solvers.create_ODE_solver(system, state_full_init, state_init, action_init, time_start=0.0, time_final=10.0, max_step=0.001, first_step=1e-06, atol=1e-05, rtol=0.001, ode_backend='SCIPY')
Create an ODE solver for the given system with the given initial conditions and integration parameters.
- Parameters
system (System) – a system object to be integrated
state_full_init (np.array) – the initial state of the system
state_init (np.array) – the initial value of the state variable
action_init (np.array) – the initial value of the action variable
time_start (float) – the start time of the integration
time_final (float) – the final time of the integration
max_step (float) – the maximum step size to be taken by the integrator
first_step (float) – the step size to be taken by the integrator at the beginning of the integration
atol (float) – the absolute tolerance for the integration
rtol (float) – the relative tolerance for the integration
ode_backend (str) – the type of ODE solver to be used, either “SCIPY” or “CASADI”
- Returns
an ODE solver object
- Return type
