\coloneqq from mathtools breaks across lines
Aditya Mahajan
I use \coloneqq from mathtools to get properly centered := symbol.
However, I was surprised to find that a break can occur between the
colon and equal to sign. Here is a minimal example (look at the colon at the
end of the first line and = in the beginning of the second line)
\listfiles
\documentclass[letterpaper,12pt,abstracton,normalheadings,DIV12,tbtags]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{mathtools}
\begin{document}
\noindent channel with input $\mathcal Z$ and output $\mathcal Y$. The plant
function $f$, the design $(C,L,G)$, $C \coloneqq (c_1, \dots, c_T)$, $L
\coloneqq (l_1, \dots, l_T)$, $G \coloneqq (g_1, \dots, g_T)$ and the cost
$\rho$ are Borel measurable with respect to appropriate $\sigma$-algebras. The
objective is to choose a design $(C,L,G)$ that minimizes the total expected
cost under that design.

Any suggestions on how to prevent the linebreak between : and =?

\providecommand*\coloneqq{\mathrel{\vcentcolon\mkern-1.2mu=}}
Will fix in source
