We study the behavior of the lowest geometric constant, $lambda_{a,b}^{c}(g)$, along the Ricci flow such that there exist positive solutions to the following partial differential equation:$$-Delta u+aulog u+bR^{c}u=lambda_{a,b}^{c}(g)u$$with $int_{M}u^{2}dmu=1$, where $a,b$ and $c$ are real constants. We drive the evolution formula for the geometric constant $lambda_{a,b}^{c}(g)$ along the unnormalized and normalized Ricci flow.
