  Let $F$ be a left invariant Randers metric on a simply connected nilpotent
Lie group $N$, induced by a left invariant Riemannian metric
${\hat{\textbf{\textit{a}}}}$ and a vector field $X$ which is
$I_{\hat{\textbf{\textit{a}}}}(M)$-invariant. If the Ricci flow equation has a
unique solution then, $(N,F)$ is a Ricci soliton if and only if $(N,F)$ is a
semialgebraic Ricci soliton.
