To achieve this, we use propositional logic to construct mathematical arguments.</p> <h2> Additional Context </h2> <p>Using discrete mathematics, we solve problems such as: ‘What is the fastest route for delivering an online order?’ Additionally, we apply this discipline to the construction of Artificial Intelligence (AI) algorithms and Databases using <strong>Graphs</strong>. <br> We can also perform algorithmic optimizations through <strong>Combinatorial Analysis</strong>. <strong>Logic</strong>, <strong>sets</strong>, and <strong>Boolean Algebra</strong> allow us to design optimized electronic circuits and more efficient distributed systems. These are just a few of the myriad possibilities of discrete mathematics. <br> In the academic context of Computer Science courses, we apply these concepts to the study of Data Structures, Algorithms, Databases, Compilers, Automata, and much more</p> <p>I leave this book as a reference and recommendation: ‘<a href="https://www.amazon.com/Discrete-Mathematics-Its-Applications-Seventh/dp/0073383090">Discrete Mathematics and Its Applications</a>,’ by Kenneth H. Rosen, published by McGraw-Hill.
