Ha, how about Excessive use may increase heartbeat.
Don't know if it's supposed to read Lover ate, or Love rate.

Well ... I'm afraid the sign has nothing to do with amorous perfrmances and/or the ingestion of viands ... maybe I should have posted:
LOVETEAR

Well, it's certainly a sign that will increase your heartrate.

That's not a helpful sign, that's a hopeful sign ... LOL ... but as I said earlier, nothing to do with love ...

OP + reply #3 suggests it's an anagram, and the anagram generator suggest it might be elevator
And it only took me eleven years to find the answer!

If I were to write an anagram generator myself what would the algorithm be?
Generate N! strings from the input and then do a dictionary look up if the generated string constitutes a "word"?

I'd process the dictionary first, creating a trie, and then take every path that you have a letter for.
Lots of permutation won't give words, but this way you waste very little effort.
If you want the anagram to be a single word from all the letters, then a good way is to preprocess the dictionary to pairs of character_sorted_words -> word.

Yes, I see.
I tried these guys and they generate not one word but multiple.
For testing purposes I submitted a 12-character "encyclopedia" and they snapped right back in about 1 second with 3672 results. Pretty impressive. That's 12! = 479,001,600 one-word permutations alone. An iterative algorithm, may be?

The results seem to be presented in order of the number of words in the anagram, and they don't give permutations of a multi-word anagram.
You can pretty easily find the longest words that use a subset of a set of characters, by just keeping character count and checking a whole dictionary (max a few million words).
And then, as you say, iterate to find words for the remaining characters.
It's also easily optimized by dividing the dictionary into word-sizes (if you have 5 characters left to match, you don't need to check 6+ characters words).
Another optimization is to match the next word so it will be greater or equal to the words after that (otherwise you waste effort by matching a give word in different positions)
At no point do you actually need to generate any permutations.

You can (or could a few decades ago) get anagram dictionaries which listed strings of letters (each arranged in alphabetical order) and the words that broke down to those strings.

Something like "aabcort = acrobat, cobra at, boat car", etc.
Found one book on amazon "Crossword Anagram Dictionary" by R. Edwards from 1979.
Thanks.

Hmm, yes, given a dictionary, it's easy to just precompute all anagrams up to a certain size.
Might be a bit big though.

My impression is that they're more like:
aaadkrrv: Aardvark
aabcort: Acrobat
...
aet: Ate; Eat; Eta; Tea
...
Rather than listing every possible string of words for a given combination of letters, they just list every single word anagram for that combination.
I could be wrong, but that's how I would have done it - that way, you only need to list as many words as there are in your source dictionary rather than coming up with an arbitrary string length to consider.

Your word is good enough for me.
I was thinking of an alternate scheme. From the definition of the anagram it follows that 1) word sizes must be the same (as towr noted) and 2) the order of characters within the given size words doesn't matter - only their presence. Hence - bit masks and Anagrammatic Sum or Signature to make comparisons in O(1) time, calculated thus.
Assume our "alphabet" has N = 3 characters: {a, e, t}. Pick the base == N + 1 = 4. Assign a Mask Value to each alphabet character:
MV( a ) = 1, (base to zeroth power)
MV( e ) = 4, (base to first)
MV( t ) = 16, (base to second), etc.
Now (in linear time) step through the dictionary and capture the words' sizes and their Anagrammatic Sums (AS):
AS( "ate" ) = 1 + 16 + 4 = 21
AS( "tea" ) = 16 + 4 + 1 = 21
AS( "tee" ) = 16 + 4 + 4 = 24
Then - if AS()s match - you've got an anagram, printf(). Obviously compare only the words of the size == strlen( input string ).
Weak spot - realistic base. The English alphabet is 26-characters long so 27 should be the base. However, extremely long (scientific) words will not fit into this scheme.

One simple scheme would to just use a bitstring of 1s separated by 0's. Most words would fit into a 64-bit word: 26 letters in the alphabet means 25 separators (0) and 39 counters (1). So e.g. abc = 101010...., aac = 110010.... etc.
