The latest memoization sources are in the Memoization-1.0 directory. You can get individual files from there or the entire directory from Memoization-1.0.tar or Memoization-1.0.tar.Z. Version-0.9.tar is the first (beta) release. See Memoization-Overview.text and README in the Memoization-1.0 directory for more information on the automatic memoization facility. Simple-Metering.lisp contains two minor hacks: WITH-FUNCTION-CALL-COUNTING will execute a body of code while keeping track of how many times specified functions are called. BREAKON tells the system to do a BREAK when the specified function is entered. See the file header for more details. CLOS-Utilities.lisp contains a class defining macro and a bunch of bookkeeping utilities to reference and retrieve instances by name, get all instances of a given class, and such. See the file header for more details. - Marty Hall hall@aplcenmp.apl.jhu.edu, hall@cs.umbc.edu (410) 792-6000 x3440
