The International Symposium on Parameterized and Exact Computation (IPEC) is an annual conference covering all aspects of parameterized and exact algorithms and complexity. Its 21st edition will be part of ALGO 2026, which also hosts ESA 2026 and other specialized conferences and workshops.

The topics include but are not limited to:

• 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 500 lines of the submission (equivalent to around 12 pages) should be enough to assess the paper and contain a summary of the main results, their motivation and importance, and evidence of their correctness. In particular, PC members and potential subreviewers may treat the first 500 lines as the short version (the rest being read at their discretion). For further details on the submission and coi guidelines and for the submission link, please refer to our website: https://algo-conference.org/2026/ipec/
