Tsitouras method of order 5 (adaptive step size ODE solver).

This solver is implemented by the Diffrax library, see diffrax.Tsit5.


  • rtol

    Relative tolerance.

  • atol

    Absolute tolerance.

  • safety_factor

    Safety factor for adaptive step sizing.

  • min_factor

    Minimum factor for adaptive step sizing.

  • max_factor

    Maximum factor for adaptive step sizing.

  • max_steps

    Maximum number of steps.

Supported gradients

This solver supports differentiation with dq.gradient.Autograd and dq.gradient.CheckpointAutograd.
