		<title>Optimal search is easy</title>
		<description><![CDATA[Last time we looked at how to solve the eight puzzle using the hill climbing algorithm, which gave us a result much more quickly than a blind depth-first search did, but we wondered if the solution we found was the best we could do, and we asked if there was a way to use heuristics [...]]]></description>

		<title>Heuristics are easy</title>
		<description><![CDATA[(This post assumes you read the previous one.)
Today we&#8217;ll be looking at the hill climbing algorithm, which is just a plain old depth-first search with heuristics added.
&#8220;Heuristics&#8221; is a fancy word (from the Greek εὑρίσκω, &#8220;I discover&#8221;) for a very simple concept. In the context of search trees, it simply means that at a every [...]]]></description>

		<title>Search trees are easy</title>
		<description><![CDATA[A decent proportion of my readers are noobie programmers or people who aren&#8217;t in a position to receive a formal CS education, so I thought I&#8217;d cover the basics of a fundamental concept most people cover in their first semester of algorithms or AI today: search trees. The fact that my college considers this to [...]]]></description>

		<title>Xlib hates me</title>
		<description><![CDATA[Having finished another popsci book on chaos theory recently (Ian Stewart&#8217;s Does God Play Dice?), I thought it&#8217;d be an interesting exercise to visualise the Lorenz attractor, and since it&#8217;s been a while since I&#8217;ve done anything new in programming, to take the opportunity to get into Xlib, the X Window System C library. Results [...]]]></description>

		<title>Overshot a bit</title>
		<description><![CDATA[It&#8217;s probably unlikely that I&#8217;m going to finish another book in the five and a half hours left in 2009, so I&#8217;m going to post this while we&#8217;re waiting for snacks.
I don&#8217;t have any bad habits, so my only New Year&#8217;s resolution tends to be to read fifty books in a year. Last year I [...]]]></description>

		<title>ISBN and EAN</title>
		<description><![CDATA[My social and academic environments aren&#8217;t exactly intellectually stimulating, so I get most of the programming problems I fill my days with&#8212;and of which the ones that are the most fun to talk about end up here&#8212;from books I read. Since I&#8217;ve already read every interesting sciencey non-fiction book available in Leuven, I&#8217;ve mostly been [...]]]></description>

		<title>Cisco sucks at crypto</title>
		<description><![CDATA[I&#8217;m in a class called Netwerkbeheer (Network Management), which spans two semesters and is a transparent excuse to peddle CCNA certifications. As a result, I spend a lot of time playing with Cisco routers and switches, and one of the many, many things that annoy me about Cisco&#8217;s IOS is their cavalier attitude towards security [...]]]></description>

		<title>Afrikaners don&#8217;t know what the hell they&#8217;re talking about</title>
		<description><![CDATA[I&#8217;m not even talking about apartheid or AIDS. I&#8217;m talking about language. Quite apart from the fact that they incomprehensibly keep pretending their dialect is a language in its own right, they keep applying the wrong words to things, and then passing them on to other languages.
Three examples.

Exhibit A: Meerkat





This is probably the most famous [...]]]></description>
