simulated annealing optimization and importance-sampling
Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems.
FTimes is a system baselining and evidence collection tool. The primary purpose of ftimes is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis.
Pascal Units for Medical Applications
The PUMA Repository is a collection of Pascal units for medical informatics. It contains reusable source code for a wide field of health-care application development. The code includes converting functions for measurement units and an HL7 engine. PUMA is compatible with Lazarus and Free Pascal. Some of the units also support other Pascal implementations including Delphi, winsoft Pocket Studio and other compilers.
