Prediction with Neural Networks

Hello, i am Neural Network apprentice, i am learning that on university. Currently i am developing a round based RPG, and got stuck in decision making as you can read in my previous post due performance issues. So i would love to give a solution with ANN a try... Example Situation Lets assume a simple Situation 1 vs 1: 1 Healer (AI) vs 1 Tank (enemy) on your turn, the Healer can attack, or he can heal. that turns out into 4 possible actions you can do: a) Attack yourself (=healer) b) Attack the Tank c) Heal yourself d) Heal the Tank So decisions b) and c) are good ones, and a) and d) are stupid ones. Scoring i have written a scoring algorithm that determines on how good your actual state on the battlefield is, depending on current health and so on. bad situation < 0 < good situation. I am interested in a near future situation: "How does my decision now affect the resulst within x (= 5?) turns ?" I can do a calculation over a decision tree and calculate a score for each path in the decision tree. this works, and i get good results. The only problem is, that i would need a Earthsimulator2 machine in order to get the Scores within an acceptable time.... The Network So heres the idea of the neural networks come into play: If i could feed a neural network with the data of the current situation (current health, skills, affected states like poisoned, stunned aso.) and the planned action as input value, and i want to get a forecast of the input after x (= 5?) rounds as output, The Training I train the network with example situations. I calculate the outgoings of an action within x rounds, and take the average of them. i use this average value for training the network for the same input like in my calculation. Execution In execution phase, i know the 4 possible actions, and ask the network 4 times to give a prediction, then i choose the action that has the best value. Type of Networks I am really new to ANN, and currently have no idea, what kind of network suits best to solve that problem. What do you think ? i this goal possible to achive, or is this completly nonsense ? thanks for reading, Tom
