Help the missionaries and cannibals over the river
ARGH! HELP!

D'oh, I didn't think one thing through, got it now.

Damn it, I USED to know the answer to this.

AHA!

What sort of help do you want?

As a hint...work out what the conditions need to be for two missionaries to row across...

The next one is even better :)

This is irritating the hell out of me!!! GRRR

I am logically deprived...

For two missionaries to row across together, leaving one behind, there needs to be exactly one cannibal on the right bank. If there were two, then the left behind missionary gets eaten. If zero, then the two rowing missionaries will get eaten when they get to the other side.

So, at some point you need

That's quite easy to get to, and it's straightforward from there.

Once you get the concept behind it, it's easy.

It would be better if it were real-time, instead of eight seconds taking about twenty.

Well...it's a logic problem, not an FPS...

I made one minor thinking error with the eating condition...

Once you get to a symmetrical position, complete it by reversing how you got there.

Easy :-D

Yeah; once you twig that a cannibal in a boat with a missionary will eat his co-pilot instantly on arrival at a bank with only cannibals, rather than them having to getr out of the boat first, it's a cakewalk.

*embarassed look*

I still can't manage it!

Yes I can :-)
