Discrete Mathematics
Logic, proof, induction, relations, counting, recurrences, graphs, automata and complexity: the discrete maths of a first university course.
A complete first university course in discrete mathematics, in the order it is usually taught: propositional and predicate logic and the standard proof techniques; induction in all its forms; sets, relations and functions, including countable and uncountable sets; counting with the product rule, bijections and the pigeonhole principle; recurrence relations and how to solve them; graphs, trees, Euler and Hamilton paths and colouring; Boolean algebra, circuits and finite automata; and finally algorithms, asymptotic analysis, the master theorem, satisfiability and polynomial-time reductions.
It is for anyone comfortable with school algebra who wants to reason precisely about finite and countable structures, and it is the mathematical core of a computer science degree. Each unit ends with a quiz mixing computation, concepts and short proofs; the final exam covers the whole course.

Ujian akhir.
Soalan dari setiap unit, yang paling sukar terakhir. Jawapan yang ditandakan oleh sistem algebra; bukti dan kerja yang difoto dibaca oleh model; kemudian seseorang meninjau keseluruhan kertas sebelum hasil anda dikeluarkan. lulus dan anda mendapat sijil dengan pautan sendiri. Tanda lulus: 70%.
