comment Finding gradient of an optimization
@Dirk you're right. the relaxed variable $w$ would be better. I have modified my question, now. well because in each step $w$ would be changed to a new one then from the equation the heat $T(t_i, w)$ would change, too. Maybe if I say that $T(t_i, w)$ is updating in each step, rather would be better.

comment How to model a time-discrete heat equation on a graph?
@DelioMungnolo: Because I aim at measuring temperature in some arbitrary vertices after modeling, then I guess(not sure) this wont lead to what I have in mind(edge-based identification problem). I would like to use incidence matrix and, consequently, one can use Laplacian matrix as well.

comment Heat equation with graph laplacian
@DelioMugnolo I was deleting some unanswered old questions that unfortunately that question was among of them and I did wrong. This is why I posted it again.

comment positive semidefinite matrix condition
I want to have an embedding model in terms of column of $V$, i.e. $v_i$'s.
