[racket-users] Re: Amazon Mechanical Turk library/package in racket

This has been on my Racket wish-list for a while.  I just haven't had a 
chance to put something together.

But I've done a lot of work with Turk and its APIs in the past, so if 
someone were to start a project, I'd be happy to help out with it...

Re: [racket-users] continuations for search

2019-09-12 Thread Laurent
Hendrik,

There is also the all too often forgotten iterative deepening depth-first
search algorithm:
https://en.wikipedia.org/wiki/Iterative_deepening_depth-first_search
which has the advantages of both, at a very small cost in search time
compared to doing depth-first search with the right cut-off depth bound
from the start.

There are several other considerations to ponder regarding which algorithm
is the right one (backward model, state size, duplicate checking, cost of
continuations, size growth of the search tree, etc.), but I'll abstain for
now unless you want more details.
