| Outline of Research at the Start |
1. provide new definitions of main equilibrium concepts: subgame perfect, perfect,
sequential equilibrium, and quasi-perfect equilibrium that are suitable for the games without perfect recall;
2. formulate and prove series of theorems that describe properties of the newly define concepts: their existence and relationships among them;
3. investigate the implications of the theoretical findings for decision-making in situations when agents do not have perfect recall: what is the optimal way of making sequential strategic decisions when full information about the past is not available.

| Outline of Annual Research Achievements |
The second research paper (current title: "A re-examination of the equivalence of strategies in finite extensive form games") was presented by Dmitriy Kvasov at the 18th European Conference on Game Theory (University of Messina, June 26-28, 2023).
During Professor John Hillas's research visit to Maastricht University (September 17 - October 15, 2023), the final revision of the second research paper was completed, and it was submitted for peer review to Games and Economic Behaviour.
The revised version of the third paper (provisional title: "On the absent-minded driver game") has been completed and is set to be submitted for peer review to a leading journal in the field (Games and Economic Behaviour or the International Journal of Game Theory).

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Research visit by Professor Hillas was instrumental in completing the second research paper.
Presentations of the research results at invited seminars and at the SING18 conference generated valuable feedback, significantly enhancing the progress of the project.
|
| Strategy for Future Research Activity |
Based on the results of peer review, the second paper will either be prepared for publication or revised and resubmitted for the second round of peer review.
The final version of the third paper is to be completed, and the paper will then be submitted for peer review.
