How to force LaTeX to 'hyphenate' (monospaced font)

Question

How can I force LaTeX to 'hyphenate' the following text? Such that the margins are not overridden (see picture). Is there a way to prevent this?

Edit: This is the file after adding -

\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{lmodern}
\geometry{a4paper,left=25mm,right=25mm, top=2cm, bottom=2cm} 
\begin{document}
\noindent \texttt{LinearDiscriminantAnalysis}, \texttt{QuadraticDiscriminantAnalysis}, \texttt{Perceptron}, \texttt{GaussianNB}, \texttt{LogisticRegression}, \texttt{DecisionTreeClassifier}, \texttt{SVC}, \texttt{MLPClassifier} and \texttt{KNeighborsClassifier}.\\
\\

Excepteur sint obcaecat cupiditat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

Answer 1

(edited answer to incorporate OP's second, supplemental example)

As David Carlisle has already observed in a comment, LaTeX doesn't "do" hyphenation with monospaced font faces. However, this can be overridden by inserting \- hyphenation points. Assuming that it's ok to hyphenate GaussianNB as Gaus\-sian\-NB, and assuming further that it's permissible to exchange the ordering of the final two terms, the following solution gets the job done. A similar approach works with the OP's second example as well.

\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{hmargin=25mm, vmargin=2cm} 
\usepackage{lmodern}
\usepackage[ngerman]{babel}

\begin{document}
\hrule % just to illustrate width of textblock

\smallskip\noindent 
\texttt{LinearDiscriminantAnalysis}, 
\texttt{QuadraticDiscriminantAnalysis}, 
\texttt{Perceptron}, 
\texttt{Gaus\-sian\-NB}, 
\texttt{LogisticRegression}, 
\texttt{DecisionTreeClassifier}, 
\texttt{SVC}, 
\texttt{KNeighborsClassifier} and % exchange order of final two terms
\texttt{MLPClassifier}.

\medskip\noindent 
portiert werden. Hierzu z"ahlen die Klassen
\texttt{LinearDiscriminantAnalysis}, 
\texttt{Quadratic\-DiscriminantAnalysis}, 
\texttt{Perceptron}, 
\texttt{GaussianNB}, 
\texttt{LogisticRegression}, 
\texttt{SVC}, 
\texttt{Deci\-sion\-TreeClassifier}, 
\texttt{MLPClassifier} and 
\texttt{KNeighborsClassifier}.

This uses \sloppy to allow extra white space and adds automatic \- if a lower case letter of followed by a capital, I show several widths, to show hyphenation.

\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{lmodern}

\def\zzz#1{\texttt{\zzzuc#1\relax}}

\def\zzzuc#1{%
\ifx\relax#1%
\else
#1%
\ifnum\lccode`#1=`#1 %
 \expandafter\expandafter\expandafter\zzzlc
\else
  \expandafter\expandafter\expandafter\zzzuc
\fi
\fi}
\def\zzzlc#1{%
\ifx\relax#1%
\else
\ifnum\lccode`#1=`#1 %
 #1\expandafter\expandafter\expandafter\zzzlc
\else
 \-#1\expandafter\expandafter\expandafter\zzzuc
\fi
\fi}

\usepackage{parskip}
\sloppy

\geometry{a4paper,left=25mm,right=25mm, top=2cm, bottom=2cm} 
\begin{document}
\zzz{LinearDiscriminantAnalysis}, \zzz{QuadraticDiscriminantAnalysis},
\zzz{Perceptron}, \zzz{GaussianNB}, \zzz{LogisticRegression},
\zzz{DecisionTreeClassifier}, \zzz{SVC}, \zzz{MLPClassifier} and
\zzz{KNeighborsClassifier}.

Using babel you have a sophisticated toolbox for this problem. If you can read Geman then here's an excellent overview:

http://homepage.ruhr-uni-bochum.de/Georg.Verweyen/silbentrennung.html

I try to translate a bit:

• - Creates a dash. Only at this position is hyphenation possible.
• "= Creates a dash whether or not hyphenation occurs. Hyphenation is possible at this position; hyphenation at other positions may also be possible. The advantage of writing, say, Schmutzwasser"=Auffangbecken instead of Schmutzwasser-Auffangbecken is that the former expression permits hyphenation inside the sub-words Schmutzwasser and Auffangbecken.
• "~ Creates a non-breaking dash. At this position, no hyphenation is possible.
• \- Does not create a dash unless hyphenation occurs. Hyphenation is possible only at positions indicated by \-. This is useful for one-off hyphenation needs, e.g., in the words Decision\-Tree\-Classifier and MLP\-Classi\-fier. (Such words will, in general, not be covered by babel's hyphenation rules.) Note that \- "works" even on words typeset in a monospaced font.
• "" At this position a line break is possible, but no dash is shown in case a line break occurs.
