Yes the sauce is in the algorithm and its a non-trivial one. Its a NP hard problem of searching through a combinatorial explosion of possible configuration. I am not aware of any other product that comes close to what ITA offered. The feature of Lisp that was heavily used in the code was the use of macros and metaprogramming. These are the kinds of problems were lisp excels. ITA made use of the fact that Lisp is a programmable programming language and they adapted programming language to the domain.
