I just want some piece of pseudo code (below) to stand out in my algorithm. So I made the all the keywords (if, end for etc) unbold with

`\AtBeginEnvironment{algorithmic}{\let\textbf\relax}`

. Now how I can make this code bold? I am posting the part that needs to be bold.

```
\documentclass[11pt]{article}
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox
\AtBeginEnvironment{algorithmic}{\let\textbf\relax}
\usepackage{amsmath}
\usepackage[fleqn]{mathtools}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{fontspec}
\usepackage{bm}
\newcommand*\Let[2]{\State #1 $\gets$ #2}
\algrenewcommand\alglinenumber[1]{
{\sf\footnotesize\addfontfeatures{Colour=888888,Numbers=Monospaced}#1}}
\begin{document}
\begin{algorithm}
\begin{algorithmic}[1]
\State //Explo. Loop
\For{\texttt{$i$ from 1 to $S$}}
\State //Take an exploration step for bacterium {$i$}
\If {$E_t$ = $M_t$}
\Let {$\theta(i,j+1,k)$} random position
\State {$J_{last}$} = {$J(\theta(i,j+1,k))$}
\If {$J_{last}$ < $J(i,j,k)$}
\Let {$J(i,j+1,l)$} {$J_{last}$}
\EndIf
\State end //if
\State {$E_t$} = 0
\EndIf
\State end //if
\EndFor
\State end //Explo. Loop
\State // Exploitation Loop
\For{\texttt{i from 1 to $S$}}
\If {$E_r$ = $M_r$} let bacterium undergo:
\State (Eq. 7)
\State (Eq. 8)
\State (Eq. 9)
\EndIf
\State end //if
\EndFor
\State end //Explo. Loop
\end{algorithmic}
\end{algorithm}
\end{document}
```

## Best Answer

I think it's a bad idea to remove

`\textbf`

in that way, but it's an even worse idea to make all the environment boldface.The algorithm will already stick out by itself, and the boldface keywords help the reader in finding the key places.

However, if you really want to follow this path, just add

`\bfseries\boldmath`

to your environment.
