  author={Dongdong Ge and Simai He and Zizhuo Wang and Yinyu Ye and Shuzhong Zhang},
This paper presents a general technique to develop approximation algorithms for allocation problems with integral assignment constraints. The core of the method is a randomized dependent rounding scheme, called geometric rounding, which yields termwise rounding ratios (in expectation), while emphasizing the strong correlation between events. We further explore the intrinsic geometric structure and general theoretical properties of this rounding scheme. First we will apply the geometric rounding… CONTINUE READING
