Towards Fairness in Online Service with k Servers and its Application on Fair Food Delivery

1 code implementation18 Dec 2023 Daman Deep Singh, Amit Kumar, Abhijnan Chakraborty

In this paper, we introduce a realistic generalization of k-SERVER without such assumptions - the k-FOOD problem, where requests with source-destination locations and an associated pickup time window arrive in an online fashion, and each has to be served by exactly one of the available k servers.
