我可以在本地切换到“贪婪”的证明算法吗？

我对此并不乐观，因为这是 TeX 算法的核心部分，但有没有办法切换到“贪婪”的对齐算法？也就是说，不是对整个段落进行处理并优化单词间距，而是尽可能多地将内容放在一行上，必要时使用连字符，对齐，然后移至下一行。

本着永不言败的原则，这将逐行构建段落（首先使用正常设置）....

您可以让 TeX 对连续的视觉不兼容的行不那么挑剔，更喜欢连字符，并且对糟糕的间距非常宽容。

\documentclass{article}
\usepackage{kantlipsum}

\begin{document}

\kant[1]

\adjdemerits=-1000000 % demerits for consecutive visually incompatible lines
\hyphenpenalty=-5000  % penalty added for hyphenating
\doublehyphendemerits=-1000000 % demerits for consecutive hyphens
\tolerance=10000 % bad lines are OK

\kant[1]

这是另一次尝试。第三段已使用“贪婪”方法手动拆分，其中考虑到\righthyphenmin=3。

\documentclass{article}
\usepackage{kantlipsum}

\begin{document}

\kant[1]

\adjdemerits=0 % don't be fussy about consecutive visually incompatible lines
\hyphenpenalty=-5000 % prefer hyphenation
\doublehyphendemerits=-1000000 % consecutive hyphens are OK
\tolerance=50 % be strict as regards to spacing
\linepenalty=9999 % as few lines as possible

\kant[1]

\newcommand{\aline}[1]{\hbox to \textwidth{#1}}

\aline{\indent As any dedicated reader can clearly see, the Ideal of practical reason is a rep-}
\aline{resentation of, as far as I know, the things in themselves; as I have shown else-}

前四行一致，然后 TeX 的算法开始执行。

将尽可能多的内容放在一行上，必要时使用连字符，对齐，然后移至下一行。

这是一个完全忽略连字符规则的解决方案，只要行满了就会进行连字符连接。

\def\greedybreak#1{#1\ifx#1\blankspace\else\discretionary{-}{-}{}\fi}

\setuppapersize[A5]

\showframe
\starttext

\input ward

\bgroup
\setupalign[normal,verytolerant,stretch]
\handletokens 
The Earth, as a habitat for animal life, is in old age and
has a fatal illness. Several, in fact. It would be happening
whether humans had ever evolved or not. But our presence is
like the effect of an old-age patient who smokes many packs
of cigarettes per day---and we humans are the cigarettes.

这是略有不同的测试文件的结果。

该算法可以稍微智能一些，以便不在标点符号前使用连字符:)（并\dicretionary正确使用命令；现在我也将把带有连字符的图像留在行首）。
