Default component needed

hello guys i'm targeting this task:
an object A will reach the object B
the algorithm will find the path (link) between them not according to the distance ( it's NOT required to find the shortest path) but according to another criteria...something similar to the criteria that we give to a database to sort the results... something like that...
the programming language is not important to me...

thank you.

You mean according to priority?
What are you trying to do exactly. Be more clear and specific.

well take the airplans as example if a user wants to go from airport a to airport b he can go directly...
as direct way:
high cost
less time

as passing By airport C and D
less cost
more time

and so on...

i need a component that does not only find the shortest way (direct way)

the user need to travel with the path that have for example the lowest cost or an average cost, hope that you got the idea

I don't really know if i got what you mean, therefore i created something that is more general and you can manipulate the way you wish. I used PHP to do it, since you didn't want database i had to use Array tree structure. You can add as much elements to the last array in the tree (price...) and it will be displayed in the output =)
Sorry for not doing the input form... i gotta go to bed, i've been awake all night.

sorry for not having the time to mak ethe component but i can tell you how you can send a user from airport C to airport D, it's so simple...

Quote:
$airportC = array(
1 => "Elie",
2 => "Ibrahim",
3 => "Samir",
);

$airportD = array(
1 => "Jean",
2 => "Peter",
3 => "Sony",
);
$user=$airportD[3];

array_push($airportC, $user);
print_r($airportC);exit;
you see? with this simple code sony went from airport D to airport C
I hope this can helps you ..

thank you xcoder, hegma and google for your care...i need it similar to what xcoder provided.
i need the system to do the following steps
first get from the user the departure airport A and the arrival airport B
the system will look at all the airports linked to A the results are B C and D
the system will take each possible path
A-B
A-C-B
A-D-B
A-C-D-B
and calculate the distance time and cost for each path
then the user will select to display the results filtered according to his needed criteria maybe he need the cheapest one or maybe the timeless one.
as example:

A-B:
high cost
less time
less distance

A-C-B:
considerable cost
more time
more distance

A-D-B:
Low cost
much more time
more distance

the use of the database is only to save the information, i can code it from scratch but if i could find a similar component available it will be better

The use of the database is way more than storing data, your system could work way better using a DB, you can group and order to get your results with minimum and maximum....
