Your guide to the functional programming paradigm Functional programming mainly sees use in math computations, including those used in Artificial Intelligence and gaming. This programming paradigm makes algorithms used for math calculations easier to understand and provides a concise method of coding algorithms by people who aren't developers.

The pure approach is best suited to researchers who have no desire to create production code but do need to test algorithms fully and demonstrate their usefulness to peers. The impure approach is best suited to production environments because it's possible to mix coding paradigms in a single application to produce a result more quickly.

Since its first appearance in 2008, this book has changed the landscape of Virgilian studies. Analysing closely the logic and the literary genres of Virgil's three poems, it politely confronts the modern orthodoxy that Virgil signalled distaste for the methods of his ruler, Octavian-Augustus. It refreshes the study of Virgil's poetry by comparing it with the detail (normally neglected by scholars) of Rome's civil wars after Julius Caesar's death, when Octavian's survival looked highly unlikely. And it argues that Virgil wrote as a passionate - and brave - partisan of Octavian, who - like a good lawyer - confronted his patron's undeniable failings in order to defend. Awarded in 2011 the prize of the Vergilian Society for 'the book that makes the greatest contribution toward our understanding and appreciation of Virgil'.
