How to velocity update in PSO?

I have 1000 room each room has inside different cash and also all the rooms are closed on initial state.

At that time 5 rooms only to be permitted to open and get a cash from respective rooms only.for example room 1 has Rs 200, room 2 has Rs 300, room 3 has Rs 700, room 4 has Rs 800 and so on upto room 1000. My objective is to get a maximum amount when i opened 5rooms ? Here i hope to using Particle Swarm Optimization Technique. Step 1: I initialize randomly 100*5 size array for ex A=[1 4 2 6 7; 2 3 6 7 8; 2 5 7 10 210] and so on Note:Value indicates room numbers. And the row indicates at that time 5rooms[1 4 2 6 7] only opened.

How to velocity update this PSO problem???

Hai sir i slight changes my objective function to your code .In velocity updation i got is float value and also repeated value is . x=x+v x is initial random value v is velocity value after that x=x+v the x is float and also repeated value sir ...But the room number never be float value and repeated room number sir

@Vijay: Is possible to do round off of your room number.

 Y = round(X)

If using round X ,the Y may be repeated .For ex X=[4.566 6 8 9 4.99] if round(X) ieee Y=[5 6 8 9 5] The room number 5 repeated.....
