我创建了以下算法，但我对输出不满意。所以我想知道是否有一种方法可以在我的算法中添加垂直线，同时保持相同的结构，并能够将其放在颜色框中。PS
：我在单独的文件中使用了此代码，并将其包含在我的主文件中。
这是我的代码：
\tcbset{
enhanced,
left=5mm,
right=8mm,
boxrule=0.4pt,
colback=blue!5!white,
boxrule=0.1pt,
%colframe=red!75!black,
colframe=blue!75!black,
fonttitle=\bfseries
}
\setuldepth{Berlin}
\begin{tcolorbox}[
lifted shadow={1mm}{-2mm}{3mm}{0.1mm}%
{black!50!white}%,width=\textwidth
]
\centering
\begin{algorithmic}
\item Given an initiator agent A representing the Cloud Service Costumer(CSC), an agent B representing candidate cloud service provider (CSPs) among many others, a set of negotiable
parameters of Saas contract.
\begin{enumerate}
\item[\textit{1.}]The initiator agent A sends a call for proposal (cfp) to the agent B.
\item[\textit{2.}]The agent B evaluates the call for proposal using an internal
function “evaluate proposal”.
\item[\textit{3.}]The previous evaluation allows agent B to make a decision, either
it responds by a \textit{proposal} or a \textit{rejection} (refuse).
\item[\textit{4.}]\ul{\textbf{If }} response(B) = rejection \ul{\textbf{Then}}The agent A eliminates the agent B from being selected for negotiation.
\item[ ]\ul{\textbf{ Else}}
\begin{description}
\item[ ] \ul{If } response(B) = proposal \ul{\textbf{Then }} The agent A evaluates the offer to select agents for negotiation using an internal function “ select for negotiation ” and either ,selects the agent B to start negotiation with, or eliminate agent B from being selected to
start negotiation with .
\item[ ]\ul{\textbf{EndIf}}
\end{description}
\item[ ]\ul{\textbf{EndIf}}
\end{enumerate}
\end{algorithmic}
\end{tcolorbox}
输出结果如下：
