DDE using boost odeint

Question

Is it possible to solve differential equations with time delay using the C ++ Boost - odeint library? For example, below the equation:

x'(t) = r*x(t)*(1 - x(t-tau)),

where tau is a constant value for time delay.

Yes, you can. But odeint is clearly not intended for DDE. There are two options for solving DDE with odeint:

You consider x and its discretized history as dependent variables and use steppers directly.
You only consider x as a dependent variable and pass the history using a system function (your rhs). But in this case, you should only use steppers that evaluate the state when multiplying timestamps, such as Euler or RK2.
