\oddsidemargin 0.0in
\textwidth 6.27in

\newcommand*{\rom}[1]{\expandafter\@slowromancap\romannumeral #1@}
\makeatother
\usepackage{epstopdf}
\usepackage{multirow}
\usepackage{amsmath, amsthm, amssymb}
\usepackage{subfig}
\linespread{1.3}
\usepackage{float}
\usepackage{enumerate}
\usepackage{enumitem}
\usepackage{multirow}
\newtheorem{lemma}{Lemma}
\newtheorem{theorem}{Theorem}
\newtheorem{corollary}{Corollary}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\usepackage{hyperref}
\begin{document}
\chapter{xxx}
dfdsfdsfd
\end{document}

Answer 1

The incompatibility here is not with hyperref, but instead with loading two sub-float packages: subcaption and subfig. Since you're using caption already, I'd stick with subcaption rather than subfig.

Other suggestions include:

• Use geometry to set your document layout/dimensions, not a4wide;
• Don't load packages twice (like amsmath and amssymb);
• Load either enumitem (preferred) or enumerate, but not both.
