hashcode: scoring pizza ingredient

[vincenzopalazzo]

a possible idea is to score the like and dislike ingredient with the idea to calculate an array of preferences between ingredients such as:

preference = like / like + dislike this value should be contained between [0, ...., 1]

Now the problem is how we select the ingredients?

Another idea, can be to use the user information and sort the user in base to this score, but here the problem is "How to calculate the score between the user and all the other?"
