Body
I think there are multiple algorithms supported because none of the algorithms are clearly the best choice in all cases. The differences are in readability of the patch output and processing time needed to generate the patch. Summarizing, this is what I understand the differences are: <ul> <li>Myers: The original algorithm as implemented in xdiff (<a href="http://www.xmailserver.org/xdiff-lib.html" rel="noreferrer">http://www.xmailserver.org/xdiff-lib.html</a> and <a href="http://www.xmailserver.org/diff2.pdf" rel="noreferrer">http://www.xmailserver.org/diff2.pdf</a>), optimizing the 'edit distance' for changed lines.</li> <li>Minimal: Myers plus trying to minimize the patch size.</li> <li>Patience: Attempts to trade readability of the patch versus patch size and processing time. See <a href="https://stackoverflow.com/questions/4045017/what-is-git-diff-patience-for">What is `git diff --patience` for?</a> and <a href="http://bramcohen.livejournal.com/73318.html" rel="noreferrer">http://bramcohen.livejournal.com/73318.html</a> or <a href="http://alfedenzo.livejournal.com/170301.html" rel="noreferrer">http://alfedenzo.livejournal.com/170301.html</a> for a description.</li> <li>Histogram: Mainly created for speed. Faster than Myers and Patience, originally developed in jgit (<a href="http://eclipse.org/jgit/" rel="noreferrer">http://eclipse.org/jgit/</a>)</li> </ul> Here is a comparison of speed for Myers, patience, and histogram: <a href="http://marc.info/?l=git&m=133103975225142&w=2" rel="noreferrer">http://marc.info/?l=git&m=133103975225142&w=2</a> Here is a comparison of diff output of Histogram vs Myers: <a href="http://marc.info/?l=git&m=138023003519837&w=2" rel="noreferrer">http://marc.info/?l=git&m=138023003519837&w=2</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
