组合数学，又称为离散数学，但有时人们也把组合数学和图论加在一起算成是离散数学。组合数学是计算机出现以后迅速发展起来的一门数学分支。计算机科学就是算法的科学，而计算机所处理的对象是离散的数据，所以离散对象的处理就成了计算机科学的核心，而研究离散对象的科学恰恰就是组合数学。组合数学的发展改变了传统数学中分析和代数占统治地位的局面-Combinatorial mathematics, also known as discrete math, but sometimes people put combinatorial mathematics and graph theory together are counted as discrete mathematics. Combinatorial mathematics are beyond the rapid development of computers with a branch of mathematics. Computer Science is the scientific method, and computer objects are handled by discrete data, so deal with discrete objects has become the core of computer science, and the study of discrete objects is precisely the combination of science and math. The development of combinatorial mathematics has changed the traditional analysis of math and algebra dominant situation
