I want to write a procedure in latex. I know the algorithmic package. But I want my function should not come with a name Algorithm 1 Func_name.
I want this.
Func_name(parameter)
{
statement 1;
statement 2;
}
Please help.

Here you go:
\documentclass{article}
\usepackage{graphicx}
\newcommand\smallarrowover[1]{\scalebox{.5}{$\overrightarrow{#1}$}}
\begin{document}
\noindent
\underline{\sf Step 1 (Update):} When an edge $e=\{u,v\}\in E[G]$ arrives, update each $Z_{\smallarrowover{ab}}$ w.r.t.
\begin{equation}
Z_{\smallarrowover{ab}}(G)\leftarrow Z_{\smallarrowover{ab}}+\mathcal M_{\smallarrowover{ab}}(u,v)+\mathcal M_{\smallarrowover{ab}}(v,u).
\end{equation}
\end{document}
This is the result:
Initially I used \vec{ab} for the arrow over ab, but that did not stretch, and putting \overrightarrow{ab} in the subscripts did not make it smaller, as you want. So I defined a new command, which needs the \graphicx package. Also, you might not need the \noindent I have at the beginning, depending on what you have before it. I put it there so the whole thing would fit on one line.
P.S. I have no experience with the algorithm or algorithmic environments.
I don't think that you can print the content of your procedure somewhere else as you have tried by \State $a\gets \Procedure{Recursion}{a}$.
You could do this by styling manually. You may use \textsc in math mode to do so. You can also add a \Comment (see in the example I provided). Instead of \textsc you may also use \Call. Sometimes either \textsc or \Call will not behave as expected.

\usepackage{algpseudocode}
\begin{document}
\begin{algorithm}
\caption{Recursion}
\begin{algorithmic}[1]
\Procedure{Recursion}{$a$}
\State $a\gets\Call{Recursion}(a)$ \Comment{Call Recursion again}
\State \textbf{return} $a$
\EndProcedure
\end{algorithmic}
\end{algorithm}
\end{document}
