Open Source Research Software
On this page, you will find information about my open source research software. This includes software implemented as part of my research on evolutionary computation, artificial intelligence, machine learning, and algorithms, including Java libraries for evolutionary computation and other metaheuristics, and code to reproduce experimental results from my published papers. It is organized into the following sections:
You can find my research software at the following sites:

Maven Central RepositoryResearch Software Libraries
The following is a list of my research software that I have released in the form of libraries and frameworks to enable ease of reuse by others.
- Chips-n-Salsa - A Java library of customizable,
hybridizable, iterative, parallel, stochastic, and self-adaptive
local search algorithms: The library includes
implementations of several stochastic local search algorithms,
including simulated annealing, hill climbers, as well as
constructive search algorithms such as stochastic sampling.
The library most extensively supports simulated annealing. It
includes several classes for representing solutions to a variety
of optimization problems. For example, the library includes a
BitVector class that implements vectors of bits, as well as
classes for representing solutions to problems where we are
searching for an optimal vector of integers or reals. For each
of the built-in representations, the library provides the most
common mutation operators for generating random neighbors of
candidate solutions. Additionally, the library provides extensive
support for permutation optimization problems, including
implementations of many different mutation operators for
permutations, and utilizing the efficiently implemented
Permutation class of the JavaPermutationTools (JPT) library.

- JavaPermutationTools: A Java library for
computation on permutations and sequences: The JavaPermutationTools
(JPT) library provides Java classes that enable representing and generating
permutations and sequences, as well as performing computation on permutations
and sequences, such as implementations of a variety of permutation distance
metrics as well as distance metrics on sequences (i.e., Strings, arrays,
and other ordered data types).

- ρμ: A Java library of Randomization enHancements and Other Math Utilities:
ρμ includes implementations of various algorithms for efficiently randomly sampling
combinations of indexes into arrays and other sequential structures. It also includes efficient
implementations of random number generation from distributions other than uniform, such as Gaussian,
Cauchy, etc. Additionally, it includes implementations of other math functions that are either needed
by the randomization utilities, or which are needed by some of our other projects.

- Performance Tests for Small Clusters: Code developed to
test the performance of a small 8 node cluster of raspberry pis. Implementations
of a few simple parallel algorithms for testing the performance of a small
cluster. Uses Java RMI for communication between master node and the worker
nodes. Also includes useful bash scripts such as for starting the RMI
servers on the worker nodes, shutting down and rebooting worker nodes
from the master node, etc.
