Title: A Case Study for Generating Strategic Game AI: From HTN Planning to Multi-Modal Learning".

Abstract: This talk reports on research done on generating strategic game AI for a particular kind of games called domination games. Domination games are a popular game sub-genre in which teams compete to control a number of locations called domination locations. Domination games are a good testbed for algorithms that integrate planning and execution because actions are non-deterministic, the environment is adversarial, and the state is partially observable. The talk discusses the results of a comparative study of a number of AI techniques to generate strategic Game AI to win domination games.

Current computer and video games are fascinating laboratories for CBR as they involve interactivity, complex situations and dynamic environments. Some games often depict rich and complex environments characterized by huge search spaces for which a strong theory does not exist. Some are real-time and very dynamic, hence posing challenges for intelligent decision making and planning. These challenging characteristics represent opportunities for case-based reasoning approaches.

The workshop on Case-Based Reasoning for Computer Games is intended for both academic researchers using games as a testbed for investigating CBR concepts and individuals exploiting CBR techniques in game development. The goal of this workshop is twofold. First we want to encourage dialog among researchers to determine the current state-of-the-art of CBR research in games and to elaborate on the main issues pertaining to the study, integration, and evaluation of CBR approaches on tasks from complex games. Second, we would like to identify clear challenge tasks in the context of computer games, so that CBR approaches can be benchmarked, and progress easily assessed.

We particularly welcome for this workshop contributions in areas that include, but are not limited to, the following:

• Case-based learning and adaptation for game playing
• Path planning using CBR
• Case-based planning and real-time decision making
• Strategy recognition and modeling using CBR
• Emotional modeling and simulation
• Interactive narrative, dialogue planning, and story generation using CBR
• Execution management of CBR components in real-time games
• Evaluation techniques for complex gaming tasks
• Tools and CBR approaches for game design
• Tools for integrating CBR techniques and gaming environments
• CBR in commercial computer games
• Lessons learned in CBR/gaming investigations
• Challenge tasks for benchmarking CBR systems in the context of games

This workshop will be held on September 12th, 2011 as part of the ICCBR 2011 workshop series in Greenwich, London, UK. This workshop is open to all interested conference participants, but may be limited by available room facilities.

We plan to include an invited speaker to summarize recent work in this area and might also invite papers from a small but diverse set of contributors. The Organizing Committee will select a subset of the submitted papers for oral presentation. Finally, time will be reserved for a session where some participants can demonstrate their gaming environments and illustrate the contributions of CBR technology.

We invite submissions of two types:

• Research and application papers: a maximum of 10 pages describing original contributions.
• Demonstration of game-related CBR systems: a maximum of 5 pages describing the gaming environment or CBR component, and why is it interesting for research on CBR and games.

Papers must be submitted in electronic form as PDF. Papers should be submitted using the Easychair system. Springer LNCS is the format required for the final camera-ready copy - Authors' instructions along with LaTeX and Word macro files are available on the web at Springer.
