FG-PAAW 2020

Fine-Grained and Parameterized Approximation Algorithms Workshop 2020 (FG-PAAW’20)

Due to some concerns regarding an online meeting, the workshop is cancelled.

July 7, 2020. Saarbrücken, Germany.

Welcome to FG-PAAW 2020

The Fine-Grained and Parameterized Approximation Algorithm Workshop 2020 is a part of ICALP 2020 satellite workshops, which will be held on July 7, 2020 in Saarbrücken, Germany as an online workshop. There is no registration fee.

Scope and Goals

Fined-Grained Complexity is the newly emerged area whose aim is to refine the theory of NP-completeness in the polynomial-time regime. The ultimate goal is to further classify polynomial-time solvable problems, both exactly and approximately, under new complexity assumptions, e.g., the Strong Exponential Time Hypothesis (SETH), the All-Pair-Shortest Paths (APSP) and the k-SUM conjecture.  This young area can also be cast as the extensions and refinement of the classical areas of Parameterized Complexity, and Approximation Algorithms, which have rich literature and well-established algorithmic and proving techniques.

The main objective of FG-PAAW 2020 is to nourish the young area of fine-grained complexity and promote the extended study of parameterized complexity and approximation algorithms into the polynomial-time solvable regime.

Topics of Interest

Any research involved at least two of these areas are welcome.

  • Fine-Grained Algorithms and Complexity.
  • Parameterized Algorithms and Complexity.
  • Approximation Algorithms and Hardness of Approximations.
  • Subexponential-Time Algorithms.
  • Lossly Kernelization
  • Efficient Polynomial-Time Approximation Schemes.


The workshop will take place as a satellite workshop at ICALP 2020 in Saarbrücken, Germany on July 7, 2020. The exact location and time will be announced later.
