Help is needed to implement genetic code to maximize the coverage in wireless sensor network.

In this case whole 2d space is divided into the equal blocks in which whole mass of the block is focused to its center and center point is known as the demand point. Here coverage ratio is given by the number of the demand points covered by the sensor nodes to the total number of the demand points. In this case area of 50*50 m^2 is taken which is divided into the 10*10 m^2 blocks. here number of sensor nodes can be used is ranged as 3 to 25 in number. Please help to solve the problem
