How to prevent indent on \listofalgorithms?

Question

How can I prevent the \listofalgorithms from being indented? I tried everything I could find on the internet, but the index of my algorithms refused to be aligned along with the title.

Here is a MWE:

\documentclass{article}
\usepackage{nomencl}
\usepackage{mathtools}
\usepackage{algorithm}
\usepackage{algpseudocode}
\numberwithin{algorithm}{section}
\begin{document}
    \renewcommand{\nomname}{List of Algorithms}
    \listofalgorithms
    \newpage
    \section{Introduction}\noindent
    Text\\
    \begin{algorithm}[H]
        \caption{Caption}
        \label{algo:caption}
        \begin{algorithmic}[1]
            \State hello world
        \end{algorithmic}
    \end{algorithm}
\end{document}

Any help is appreciated. Thanks!

The indentation is due to how the \listof macro works; it's provided by float that's loaded by algorithm. The easiest way to remove the indent is to patch that command:

\usepackage{etoolbox}
\patchcmd{\listof}{1.5em}{0pt}{}{}

The definition of \listofalgorithms is

\newcommand{\listofalgorithms}{\listof{algorithm}{\listalgorithmname}}

and \listof is

\newcommand{\listof}[2]{%
  \@ifundefined{ext@#1}
    {\float@error{#1}}
    {\@namedef{l@#1}{\@dottedtocline{1}{1.5em}{2.3em}}%
     \float@listhead{#2}%
     \begingroup\setlength{\parskip}{\z@}%
       \@starttoc{\@nameuse{ext@#1}}%
     \endgroup}%
}

So once we know that \@dottedtocline is responsible for the typesetting of the line and 1.5em is the initial indent, we're done.
