Modeling a plurality of contests at a crowdsourcing node

摘要

Crowdsourcing is described, for example, where solutions to tasks such as designing a logo, writing a piece of code or answering a question are solicited by making open calls to large scale communities. In an example, a crowdsourcing node models a plurality of contests as all-pay auctions, each contest having a task and a reward. In examples, the crowdsourcing node is arranged to set rewards for the contests so that the optimal results are received for each contest owner, those owners having provided a budget and using a utility function for each of the contests.
