There are 8 submitted student proposals for this idea

Andriy Andriychuk - "Total defence" strategy

The idea is to group own troops so they are in advantageous position and get less damage.

Sanka Darshana - "Implement a 'total defense' strategy"

The AI will decide the best movements considering the resources available, enemy positions and their types, enemy distribution and etc... The generated movements will be decided on the values of the each troop. As an example, a shaman will be more important if there are more troops with low health, and Archers if there are troops with health. So the AI will determine which actions to take depending on a list of variables in the game environment

Geoffrey Hart - Maximizing Utility

A good offense is made by identifying an opponents vulnerabilities and exploiting them. As such, a good defense is made by reducing the number of weak spots. Since there is no perfect unit and all have their own imperfections, the idea is send them out in groups of units that compliment each others strengths and weaknesses. This will allow them to rearrange themselves in a way most suitable to handle nearby enemies. Since the number of predictive steps the AI can make is limited, it can become "surprised" rather easily. Therefore, it's a good choice to maximize utility and the ability to be flexible in order to handle these surprises. Then, within action-packed skirmishes, raw processing power can be brought to bear more effectively.

Christopher Conway - Defensive AI

My goal is to develop an AI which is capable of “total defense” behavior, as opposed to the current aggressive AI. It would allow for the AI to function in scenarios like controlled retreats, unit escort, or holding a given area while minimizing unit loss.

Conor Nevin - Implementing a Total Defense AI

Implementing a defensive mode of the AI, so that it is able to heal units whilst holding ground against an advancing enemy.

Nikolay Agafonov - Line Defence Strategy

The idea of this strategy is to stick together the troops and create the defencive line. All the units should be put on hexes where they would be on the defensive in most effective way. THere would be some kinds of AI's behaviour (full retreat, banking, passive attack etc.) depending on on game factors.

Ed Kim - Total Defense AI

Often, the best defense is a good offense. In Wesnoth, lacking either can get you slaughtered. It is particularly important that the AI learn not only to consider immediate gains and losses off a linear formula, but to take other considerations into account, especially some foresight into human reactions and macroscopic army flux. Similar to a chess engine, if the AI could learn to take "next move" heuristics into account as well as consider positional strategies such as defensive formations (line, square) by taking unit relationships into account, the AI would become a much more versatile and formidable foe.
