Tsinghua University Courseware:
Combined mathematics main research meets the presence, counting and construction of a certain condition (a arrangement). Combined mathematics can be generally divided into combination counts, combined design, combined matrices, combined optimization, etc.
The first 4 chapters of this course discusses basic combined counting questions. In this course, we will configure a combined model, we will arrays from middle school mathematics, and the combined counts have been discussed to discuss how many other football like a match can be discussed.
Chapter 5 introduces the preliminary knowledge of the design and coding of the area group. Considering that students in most computer systems do not necessarily choose to work, we will linearize the core content of the linearly planned single-shaped algorithm as the content of the sixth chapter of the course.
personal opinion:
The combined mathematics is only a small branch in many branches, and the development is still very imperfect, but the application is more.
Review is a bit no mind
