I want to draw vertical lines for loops and if statement. Kindly help me out and also I didn't use any specific package

Answer 1

You have to load algorithm2e to do that easily:

\documentclass[two column,conference]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage[ruled, lined, longend, linesnumbered]{algorithm2e}

\begin{document}

\begin{algorithm}
    \caption{HD}
    \label{array-sum}
     Initialization of parameters\;
     Randomly generate population using Eq. 28\;
   \For{u=1:k}{%
     \For{s=1:i$_{c}$}{%
     Randomly generated X$_{s}^{u}$ in da \;
            }
            }
     End of initialization step\;
     \While{Maximum number of iteration reached}{
    Construction and assessment of new candidate\;
    \eIf{($rand (0,1)\leq$ cpu)}{%
     Choose random no \;
     \textbf {if} ($rand (0,1 ) \leq$ cpu) \\
     %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     \textbf{end if}
     }{%
     Evaluate fitness function a: F(a) using Eq. 17 \;
     End of the construction and assessment step\;
     Construction and assessment of new candidate: a \;
     \eIf {(F(y) has best value than the worst member}{
     Replace DA member with new candidate: a
     }{%
     Discard x}%
        }%
     End of update\;
     Until a preset termination criterion is met}
\end{algorithm}
