Rationalizing collective revealed preferences with an application in fair resource allocation
Chuwen Zhang, Zhiyun Guo, Zizhuo Wang +1
This paper presents a revealed preference approach for rationalizing collective consumption behavior. We introduce the Constructive Rationalization Method (CRM), which approximates…
Cardinal Optimizer (COPT) User Guide
Dongdong Ge, Qi Huangfu, Zizhuo Wang +2
Cardinal Optimizer is a high-performance mathematical programming solver for efficiently solving largescale optimization problem. This documentation provides basic introduction to…
Strong NP-Hardness for Sparse Optimization with Concave Penalty Functions
Yichen Chen, Dongdong Ge, Mengdi Wang +3
Consider the regularized sparse minimization problem, which involves empirical sums of loss functions for data points (each of dimension ) and a nonconvex sparsity penalty.…
Likelihood Robust Optimization for Data-driven Problems
Zizhuo Wang, Peter Glynn, Yinyu Ye
We consider optimal decision-making problems in an uncertain environment. In particular, we consider the case in which the distribution of the input is unknown, yet there is abunda…
Complexity of Unconstrained L_2-L_p Minimization
Xiaojun Chen, Dongdong Ge, Zizhuo Wang +1
We consider the unconstrained - minimization: find a minimizer of for given , and parameters , …
Close the Gaps: A Learning-while-Doing Algorithm for a Class of Single-Product Revenue Management Problems
Zizhuo Wang, Shiming Deng, Yinyu Ye
We consider a retailer selling a single product with limited on-hand inventory over a finite selling season. Customer demand arrives according to a Poisson process, the rate of whi…
