https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=314363
I'm new to differential equations with delay, and I'm trying to numerically solve the following system. The delays $\tau_i(t)$ are smooth and bounded functions of time: $$ S'(t) = d(t)(S_0(t) - S(t)) -... [differential-equations]
