COURI Symposium Abstracts, Summer 2012

Seismic Tomography and Smoothing Filters Seismic Tomography is a technique used by geologists to map the Earth's crust. Seismic Tomography is an iterative process that develops a model based on travel times of waves from explosion sites to sensors. First, travel times are gathered by using shot points and sensors. Then an optimization process begins with an initial simple model (velocity increasing monotonically with depth), is used to predict the travel times. These predictions are compared to the observed travel times, and the model is refined so that it can better match the observed data until a satisfactory solution is …

Generating Minimal T-Wise Covering Test Suites Using Constraints, Carlos A. Nieto, Martine Ceberio

COURI Symposium Abstracts, Summer 2012

Software testing is an essential part of software development that seeks quality assurance, reliability, and robustness. Unfortunately, exhaustive testing can be a very expensive, time consuming, and tedious process. With large sets of inputs, exhaustive testing can result in unpractical test suites, of size that grows exponentially with the number of input parameters.

As a way to address this growth, t-wise testing consists in focusing on test suites that only cover the interactions of the t-tuples of input parameters of the system at hand. Adding constraints further restricts the size of the test suite by limiting the possible values of …
