Query: Using LLVM-based JIT Compilation in Genetic Programming   The paper describes an approach to implementing genetic programming, which
uses the LLVM library to just-in-time compile/interpret the evolved abstract
syntax trees. The solution is described in some detail, including a parser
(based on FlexC++ and BisonC++) that can construct the trees from a simple toy
language with C-like syntax. The approach is compared with a previous
implementation (based on direct execution of trees using polymorphic functors)
in terms of execution speed.
