 : My assumption is that the boat is ''at least'' as capable as the human+wolf+goat+cabbage one, of carrying up to one occupant in addition to the human required to row it. And that the presence of one human is capable of both stopping a wolf from attacking a goat and of a goat attacking a cabbage (but, for the sake of simplicity/redundancy, not while rowing).
 : As a fall-back position (because multiple predators/prey exist), perhaps also consider that this time one human would be needed to restrain each goat-tempted wolf, ''plus'' an additional human to restrain each cabbage-tempted goat. (With 50 people, 30 goats, 20 cabbages, and 10 wolves, that would mean 10 wolf-handlers, 30 goat-handlers and 10 'idle' people (perhaps each normally carrying 2 cabbages?); the opposite assumption, that one person is needed as a protector, not a restrainer, would require 20 cabbage-carriers, 30 goat-herders and the wolves must then just pad along behind of their own (goat-hungry?) volition, and this would also demand a different approach to multi-cargo boats.)
-: I'll stick with the abstraction of one rower and one 'cargo', on the principle that multiple such journeys (with a single cargo-type) emulate a single journey of multiple (single-typd) cargo. And if there's enough space to send a 'set' of all three non-human types ''plus'' sufficient humans (in addition to the rower) to prevent in-boat car age, then there's much too trivial a solution.

 : So, anyway, with the "restrainer" allocation of humans, ten spare humans (their cabbages left on the floor) can be used to get nine of them over, whilst the tenth (at random/not necessarily the same one, per crossing/back-crossing) is designated rower.
-:At that point, the goats can be sent over (as one-by-one as necessary), with the option of either interspersed or as a bunch sending over the goat-restrainers (if the non-boated goats cannot even be trusted without individual handlers — though goats tend to be trained to flock with minimal supervision — then no more than nine goats will get followed by the euivalent now-spare goat-handlers, repeat as necessary (3 x 9-pairings, then final 3-pairings?), though actually leaving up to nine original goat-handlers behind, to save time later). Then send the cabbages over (even if it still means just one cabbage per trip!), there being sufficient goat-handlers to prevent far-shore (vegetarian) slaughter. Next, in the spirit of the original problem, bring back goats (and handlers-less-nine), in preparation for wolves(+single handler, at an appropriate juncture) and then all goats (and ''all'' remaining humans) on a third goat crossing.

 :Though, alternatively, you could also send ''all'' the original goat-handlers across (now nine excess humans on the far side), 1-to-9 of the wolves, at least one handler, the remaining wol[f|ves] and handler(s), without any back-journeys (except by the unaccompanied designated oarsman, each time before the final trip) at all points. You could also send over "cabbage then human then goat then human then wolf" on repeat, so long as there were still wolves/goats involved, or "two cabbages, three humans, three goats, one human, one wolf" times ten, with the other ('spare') humans whenever they wanted (at end, in advance, interspersed) according to taste and/or paranoia.
-:The "guardian"-human scenario is already trickier, as one human must always be a rower during the main period of the problem, leaving either one cabbage vulnerable to goat ''or'  one goat vulnerable to wolf, at all times. Unless the rower can take their 'personal' guarded responsibility back and forth in the boat with them (and protected!) at all times, regardless of what other (and number of) cargo/passenger(s) they are capable of conveying. But then this becomes just as trivial, as every "guardianed" non-human remains guarded in a simple once-over process (whatever order/mingling is possible), with the only query being as to how best (of several options) to get the unguardianed (only guarded-against!) wolves over.

 :Perhaps there's a single-solution (or 'very limited subset of exact solutions') if there's an actual stipulation that the boat can "carry C cabbages, G goats, W wolves ''or'' H humans per 'seat', and has S seats (one of which must be the human rower(s)", and that the rules of restraining/guarding be set down more precisely. And maybe differently for the boat, with at least one human having either less control (too busy rowing!) or more (is holding a bloomin' long oar, for greater reach!) over the current disposition of contents.
 :At the simplest, all the possible extensions to the problem being taken into account, the current ("guardian-orientated") setup is stymied by the rower being no longer able to guard their charge, so they leave their goat behind, deliver everyone else in one trip over (in the sufficiently large boat for everyone to be able to guard everything that needs guarding), then return for their own goat; or go with their goat, first, then come back for everyone else. But a "restraining-orientated" scenario with ''more'' difficulty in keeping the boat in proper order might develop a particularly clever (and necessary) sequence of transits more akin to the original puzzle.

 I suppose instead of being critical numbers it has to be done with critical ratios.  Gives you a little more wiggle room in the ordering of the trips and optimization but would read basically as the solution to the original but 25 times in a row.  [[Special:Contributions/108.162.241.51|108.162.241.51]]
