MDVRP input file #7

Closed mventura00 closed 1 year ago

mventura00 commented 1 year ago

Hi ! As I have been working a lot today to try to get the 'MDVRP' python program to run, I did have some questions on the input file (I used the 'p01' provided on GitHub demos/data/MDVRP). Please see attached. Do you have some sort of document that defines everything that goes into the 'input' file? That would be helpful for the user who is new.

p01_multidepot.txt

In row #1, it has: 2 4 50 4
What does the 2 mean? I assume 4 means '4 depots'. the 50 means '50 cities'. what does the other 4 mean?

In row 2-5: 0 80 (this is repeated for all rows). What does the 0 and 80 represent? Is 80 the capacity for each of the depots?

Starting on row #6, it has 1 (which is the first city). It has these values for row #6: 1 37 52 0 7 1 4 1 2 4 8

I imagine, 37 and 52 are the latitude and longitude. What does the 0 mean? And, what then do the next 7 digits (7 1 4 1 2 4 8) represent?

The last 4 rows are the attributes of the 4 depots: 51 20 20 0 0 0 0 52 30 40 0 0 0 0 53 50 30 0 0 0 0 54 60 50 0 0 0 0

So, in row #51, does the 20 20 , represent the latitude = 20 and longitude =20? What do the next 4 zeroes represent? Are they just placeholders?

I close this issue as a similar question is asked in issue #9.
