How might game theory be applied to explain behavior that appears altruistic in nature?

The game theory explains the altruistic behavior of people. According to this theory, people help others only when they know they can get benefit from it. They start to rationalize that, the person whom he is helping is much capable to return something.  

The game theory is the best way to recognize people. Through this theory, people rationalize the behavior of people. They rationalize that the behavior is proper/ rational or not for others.

The altruism is is the behavior that acts according to the self-interest of people. The game theory is the theory that put the altruism in the frame of self-interest.  

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
