The strict deadline for tool registration is July 28, 2025. Please subscribe to the CoCo mailing list to be informed about the competition.
Tool Description
Tool authors are invited to submit a one-page (excluding references of at most one additional page) system description. System descriptions will be included in the proceedings of IWC 2025 and typically highlight the distinctive features of the tool. Please submit a single latex file in EasyChair latex style. The strict deadline for tool description is August 4, 2025.
Tool Submission
CoCo 2025 will run live on StarExec Miami and so tools must be able to run on it. Submission instructions are available. Please contact the CoCo SC in case of installation problems. Each tool will be given 60 seconds (wall-clock time) and a memory limit of 128 GB on a single StarExec node per problem. After the submission deadline, tools will be tested on a few sample problems.
Panel
CoCo 2025 is overseen by a panel of knowledgeable experts who are not participating in the competition.:
