<p>This 4-part series and a 40-minute video of a summary talk covers in detail the mathematical theory and design principles used in TLA<sup>+</sup>.</p>
<ul id="posts" class="content-listing">

<h2><a href="/posts/tlaplus_part1">Part 1: The Principles of TLA<sup>+</sup></a></h2>
<p>TLA<sup>+</sup> is a formal specification and verification language intended to help engineers specify, design and reason about complex, real-life algorithms and software or hardware systems. We explore its motivation, application and principles of design.
</p>
</li>
<li class="post">
<h2><a href="/posts/tlaplus_part2">Part 2: The + in TLA<sup>+</sup></a></h2>
<p>We explore the data logic of TLA<sup>+</sup>, the means by which TLA<sup>+</sup> specifications describe a state of computation: its data structures. To do that, we first cover the basics of mathematical logic.
</p>
</li>
<li class="post">
<h2><a href="/posts/tlaplus_part3">Part 3: The (Temporal) Logic of Actions</a></h2>
<p>TLA, the Temporal Logic of Actions is the core of TLA<sup>+</sup>. It is a temporal logic that minimizes the use of temporal reasoning in favor of more ordinary mathematics. It is a general mathematical framework for describing and reasoning about algorithms and systems.
</p>
</li>
<li class="post">
<h2><a href="/posts/tlaplus_part4">Part 4: Order in TLA<sup>+</sup></a></h2>
<p>We learn how to encapsulate and compose TLA<sup>+</sup> specifications, of the precise mathematical definition of abstraction, and compare TLA<sup>+</sup>'s notion of abstraction with those of other formalisms. Plus some various cool stuff.
