IWOGL 2021

September 22 - 23, 2021
The 11th International Workshop on
Graph Labeling
FREE Registration! Must register to attend the workshop!


IWOGL is a problem-oriented series of workshops with emphasis on informal discussion. The main themes of the workshop are the topics within the following areas, but are not limited to:

  • Applications of graph labelings
  • Graceful labelings and their variations
  • Magic and antimagic type labelings
  • Sum labelings and their variations
  • Prime and vertex prime labelings
  • Binary labelings
  • Average labelings

The scientific program of the workshop will consist of invited talks and open problem sessions in all areas related to graph labeling.

The 11th International Workshop On Graph Labeling (IWOGL 2021) will be held on September 22-23, 2021, organized by University of Newcastle (Australia), University of Indonesia (Indonesia), and Technical University of Košice (Slovakia).

Open Problem Submission

In IWOGL tradition, we will hold open problems sessions at IWOGL2021. You are invited to submit an open problem to share with other conference participants or wider IWOCA community. An open problem description should not exceed 2 single-spaced pages, including references, figures, title, authors, affiliations, e-mail addresses, and the open problem description.

The authors are strongly advised to use the LaTeX style file supplied by Springer Verlag for Lecture Notes in Computer Science here, please email to kiki@sci.ui.ac.id. Open problems submitted will be uploaded to IWOGL website and made publicly accessible before the workshop. During the open problems session, the authors have chance to present the problem and have discussion with all the participants.
