Need to come up with a constraint problem for uni, so that I can model it and then eventually put into code etc.

An example (which I can't use btw) story would be:

Arranging the seating plan for a wedding reception - with rules such as 'grandad must sit next to grandma', 'auntie pat cannot sit on the same table as uncle ken' etc...

Anyone come up with a story that is similar and can be modelled by constraints and variables etc?

Cheers

Rub your hands together until there are sore, use the saw to cut the table in half, two halves make a whole, use the hole to escape the prison

uhhh

seating plan for airline

rules such as

first class can only sit in row A - B
second class in C - D

passengers with special considerations e.g

wheel chair passengers in end of row C

passengers who booked extra leg room in aisle seats X

you get the idea, plently of options for constraints and variables
