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}.\\

by default latex doesn't hyphenate tt you can reset that but it isn't really set up to hyphenate camel case either, so you may prefer to use \texttt{KNeighbors\-Classifier} — David Carlisle, May 01 '18 at 19:36
@DavidCarlisle I added - at all places that would be fine for me. It is better now but still not perfect. See added picture. — MrYouMath, May 01 '18 at 19:45
add \sloppy somewhere before the paragraph to give tex a bit of help — David Carlisle, May 01 '18 at 19:48
Please edit your LaTeX code so that it corresponds to the screenshot (or vice versa). — Mico, May 01 '18 at 19:52
unrelated but never use \\ \\ to get a blank line in the output — David Carlisle, May 01 '18 at 19:54
@DavidCarlisle What would you recommend for a blank line? And Why is \ \ not good? — MrYouMath, May 01 '18 at 19:55
@DavidCarlisle: Perfect! \sloppy solved my problem :). Do I have to stop sloppy or will it automatically end after the paragraph? — MrYouMath, May 01 '18 at 19:57
If change the type of typewriter font is an option, you could try with \usepackage{tgcursor} or with \renewcommand*\ttdefault{cmvtt}, for instance. — Fran, May 01 '18 at 20:15
you should never use \\ \\ or \noindent, see my answer where I specified that paragraphs are not indented but are set off with vertical space. You should almost never need \\ outside of tables and two consecutive ones (or one at the end of a paragraph) are always wrong and generate an underfull box of maximum (10000) badness, — David Carlisle, May 01 '18 at 20:34
@DavidCarlisle: I think I am too slow for your reasoning :D. What answer are you referring to? What is the best way to replace \ (Enter) \ (Enter) Text to obtain a new paragraph with a black line and no indenting? A link to your answer would be great. — MrYouMath, May 02 '18 at 20:00
\\ never ends a paragraph, if you want to end a paragraph use a blank line. If you want paragraphs to be offset with vertical space and no indent use a document class that uses that design or use the parskip package as I used in my answer. If you use \\ atth eend of a paragraph you will get bad layout and a warning "underfull hbox badness 10000" note that is the maximum badness, tex is telling you the output is as bad as it can be by its internal consistency checking. — David Carlisle, May 02 '18 at 20:26
@DavidCarlisle Great \usepackage{parskip} is perfect! Thank you for taking your time to share your valuable knowledge. — MrYouMath, May 02 '18 at 21:32

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.

@Dr.ManuelKuehner Sorry, I realize it's hard to find z on a German keyboard. — David Carlisle, May 01 '18 at 21:06
oh, please do mention sloppypar so it doesn't go on forever. — barbara beeton, May 01 '18 at 21:30
@barbarabeeton perhaps, although if the real document has lots of camel case programming terms and not so much mock latin text, using \sloppy globally isn't necessarily a bad choice. — David Carlisle, May 01 '18 at 21:33

(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

\texttt{SVC}, 
\texttt{Deci\-sion\-TreeClassifier}, 
\texttt{MLPClassifier} and 
\texttt{KNeighborsClassifier}.
Zur Bestimmung der G"ute werden zus"atzlich

+1: Never heard of the special case (regarding hyphenation) "monospaced" before. Good to know, — Dr. Manuel Kuehner, May 01 '18 at 19:55

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.

I am using \usepackage[ngerman]{babel}, but it does not solve the problem. – MrYouMath May 01 '18 at 19:48
@MrYouMath Wait a min – Dr. Manuel Kuehner May 01 '18 at 19:49
@MrYouMath Now, have a look :) – Dr. Manuel Kuehner May 01 '18 at 19:54
@MrYouMath In your MWE I do not spot babel. – Dr. Manuel Kuehner May 01 '18 at 19:57

Sorry, but the MWE was not using all the stuff that I had included in my preamble. I just wanted to show the problem. – MrYouMath May 01 '18 at 20:02
@MrYouMath No problem. Therefore I wrote Using babel you have a sophisticated toolbox [...]. Because my example applies to babel. That's all. I assume you speak German judging on your YouTube channel. – Dr. Manuel Kuehner May 01 '18 at 20:04
Yes, I speak german :). Btw I looked up your homepage for the animations in a pdf file but I couldn't find them. I am looking for something like this for a long time :). – MrYouMath May 01 '18 at 20:15
@MrYouMath Search the site for animate package. – Dr. Manuel Kuehner May 01 '18 at 20:17
