We investigate the existence of almost-periodic weak solutions of second-order neutral delay-differential equations with piecewise constant argument of the form (x(t) + x(t-1))(n) = qx(x[(t + 1)/2]) + f(t), , where [.] denotes the greatest integer function, q is a real nonzero constant, and f (t) is almost periodic.
