Main points of Game Theory is:
- Modelling how individuals respond to each others’ actions
- Predicting behaviour when individuals interact
- Modelling how individuals respond to each others’ actions
A game is the environment where such interactions take place, in our situation it consists of:
– A set of users: players
– Rating and scoring per users: strategies
– Benefit per Rating / scoring: payoff
- Payoffs can be based on the rating not of one participant but of all participants
- They are shown in a payoff matrix
- Modelling and understanding privacy and trust in Social Networks
Actually, ‘Add friends’ function or be a friend in this app, is a kind of Dominant Strategies:
• A dominant strategy S for User 1 is one that is the best response to every strategy of User 2.
• A strictly dominant strategy S for User 1 is one that is the strictly best response to every strategy of User 2
• There is the assumption that users have come common knowledge of possible payoffs of each other, etc
After adding friends, users can invite friends join activities or be invited to join a activity. Based on the same interests, adding friends is always the better choice for users.
