Version 0.6.0

• Add similarity(c1, c2) : Compute how similar curriculum c1 is to curriculum c2. The similarity metric is computed by comparing how many courses in c1 are also in c2, divided by the total number of courses in c2.

• Add homology(curricula; <keyword arguments>) : Given a collection of Curriculum data objects as input, provide a visulaization that shows how similar each curriculum is (in terms of shared courses) to every other curriculum in the collection.

• Add dead_end(curric, prefixes) : Finds all courses in curriculum curric that appear at the end of a path (i.e., sink vertices), and returns those courses that do not have one of the course prefixes listed in the prefixes array. This data is also added to the metrics dictionary on the curric object.

• Fixed bug in all_paths() : Will result in a change to metrics.

• optimize_plan(curric, term_count, min_cpt, max_cpt, obj_order) now supports toxic_score_file::String as a keyword argument. This should be a file path to a toxicity scores CSV.

• Adds a metadata dictionary to every data type. As the name implies this will allow for metadata to be stored on data types, such as identifying a course as a core.

• Begins testing CodeCov implementation

• Adds tests for similarity, homology, and dead_end functions.
