The International Symposium on Parameterized and Exact Computation (IPEC, https://algo-conference.org/2025/ipec/) is an annual conference covering all aspects of parameterized and exact algorithms and complexity. Its 20th edition will be held in Warsaw, Poland, as part of ALGO 2025, which also hosts ESA 2025 and other specialized conferences and workshops.

IPEC 2025 invites papers presenting original research in the area of parameterized and exact algorithms and complexity. Topics include but are not limited to the following:

• new techniques for the design and analysis of parameterized and exact algorithms;
• fixed-parameter tractability and kernelization results;
• parameterized complexity theory;
• parameterized (in)approximability results;
• relationships between parameterized complexity and traditional complexity classifications;
• applications of parameterized and exact computation;
• engineering and experimentation of exact, parameterized, and kernelization algorithms.

Submission Guidelines

We welcome submissions of the full version of the paper. Regardless, the first 12 pages (excluding the title page) should be enough to assess the paper and contain a summary of the main results, their motivation and importance, and evidence of their correctness. As previous years, IPEC 2025 uses a lightweight double-blind model for the reviewing process. For further details on the submission and coi guidelines and for the submission link, please refer to our website: https://algo-conference.org/2025/ipec/
