Is it your computer course assignment ?

# 2 Re: Hi...aLL
yes, man ,...its a computer assignment, need to be formulated and coded in java,the problem here is could we apply known algorithms such as max flows,lower bounds,have i to post the pdf file man, u have a look ??

Your url is not functional, to solve a problem you can use any algortihm that you know of, but you need to code these algorithm in Java.

sorry man, i attach the pdf file, with this reply, look u r quite right it need to be formulated first,then put a general model to solve it, then code it in java, badly i know the algorithm of maxflow, but i couldnt apply it on such problem, too hard to me, hope u could formulate it...regards;

It is a linear programming problem

You need to optimize the matrix

There are only 6! = 720 ways you can arrange your flight schedule
You just need to find out which one is optimal (e.g Boston->Washington->...)
As coding the generalization of it in java is lot of work, you may need to hire some freelance programmer.

# 7 Re: Hi...aLL
the (ri,j) matrix is of return of flights...we may use what we need from it, not forced, but what we forced to do, is the table ex: boston--> washignton a(i)=6,b(i)=7

what confuses me ( first step) is how to apply these algorithms on such a model ...thats before java coding...so i just need the general model

for more details...plz add me on msn or yahoo

no one guys could formulate such a problem ..as a network ??

The assignment is complex, so I do not think you will get somebody to do it for you for free
