This new wording does not prevent 1 man from carrying 2 torches, making it a completely different puzzle from the one NickMcG posted. My interpretation of your rules is that 4 people can cross, and only 1 need return (with both torches). My solution to this interpretation is 150:
*** Objective function ***
150
*** Crossings ***
Left bank: 5 10 15 20 30 30 35 45 50 55 65
Right bank:
Crossing 1: 5 30 30 35
Left bank: 10 15 20 45 50 55 65
Right bank: 5 30 30 35
Returns 1: 5
Left bank: 5 10 15 20 45 50 55 65
Right bank: 30 30 35
Crossing 2: 5 10 15 20
Left bank: 45 50 55 65
Right bank: 5 10 15 20 30 30 35
Returns 2: 5
Left bank: 5 45 50 55 65
Right bank: 10 15 20 30 30 35
Crossing 3: 45 50 55 65
Left bank: 5
Right bank: 10 15 20 30 30 35 45 50 55 65
Returns 3: 10
Left bank: 5 10
Right bank: 15 20 30 30 35 45 50 55 65
Crossing 4: 5 10
Left bank:
Right bank: 5 10 15 20 30 30 35 45 50 55 65
