D2 Help - Transportation

Hi,

I need help with transportation in Edexcel's d2. Specifically the stepping stone algorithm. Does the bit when you introduce theta and plus/minus it have to create a loop or not? I was told it does, but when doing exam questions, turned out it didn't?

Very confused...

I don't have the actual book, so don't know what theta is here, but when you use the "stepping stone" algorithm, you return to the initial chosen cell, so you do form a loop.

Can you post an example where they don't form a loop?
