Version 2.1

AutoMix

New in this release:

• Call to estimate_conditional_probs() is now optional
• Cleaner, better documented header.
• More documentation.
• API change: targetFunc to targetDist (this shouldn't break older programs).

Version 1.4.1

AutoMix

Minor enhancement

Added -b command line option to specify the number of samples to burn.
If it's not specified in the command line arguments, it will default to 100,000 or 10% of the RJMCMC samples, whichever is bigger.

Version 2.0

AutoMix

From 2.0 AutoMix generates by default a library that can be compiled against other programs.
Also new in this version:

• All source files in src directory.
• Deprecated user* programs (still working and compilable) in favor of library compilation.
• Cleaner public API with fewer functions and shorter prototypes.
• Single file library (automix. c and automix.h). No utils nor logwrite files.
• Silent library (no print statements to stdout).
• More comprehensive simpler tests in continuous integration.
• Documentation with tutorial program.
• Makefile does library installation.

Version 1.4

AutoMix

• Separation of automix functions and a main.c driver that uses automix functions.
• Cleaner public API in automix header.
• Full data encapsulation and amSampler data structure with allocator/deallocator.
• Complete separation of file-writing and RJMCMC runs.
• Clang-format style test in continuous integration.
• Simplified Makefile with pattern rules.
• Docs improvements.

Version 1.3

AutoMix

In this release:

• MCMC chain state variables encapsulated in a struct.
• Proposal (jumping) distribution variables encapsulated in a struct.
• Memory use improvements.
• Statistic variables encapsulated in a struct to hold run statistics.
• Created more arrays to hold statistics and separate file writing inside RJ samples.
• File writing now is done outside sampling functions.

Version 1.2

AutoMix

New in 1.2:

• Reversible jump moves moved to a separate function.
• Burn samples and final samples are treated in separate loops.
• Memory management improvements.
• Cleaner code with definitions moved to header file.

Version 1.1

AutoMix

This version includes:

• Improved command line arguments, and a usage help.
• User provided functions were refactored with descriptive variables names.
• Versioning.
• More efficient memory handling.
• Other minor improvements in automix.c.

Version 1.0

AutoMix

The AutoMix package is a C program for Unix-like systems, implementing the automatic reversible jump MCMC sampler of the same name described in Chapters 4, 5, and 6 of David Hastie's Ph.D. thesis.
