How do you envision the ways program verification and performance tuning will be accomplished in the future?

How do you envision the ways program verification and performance tuning will be accomplished in the future? Will it still be a work of art? Will it always be the result of one's experience? Or do you forecast more and more automatic ways (algorithms?) to accomplish these tasks?

What is the advantage of sparse matrices over two-dimensional matrices? How are sparse matrices different from Lists?

One of the problems of storing data in a matrix (a two-dimensional Cartesian structure) is that if not all of the elements are used, there might be quite a waste of space. In order to handle this, we can use a construct called a "sparse matrix", where only the active elements appear. Each such element is accompanied by its two indexes (the row and the column). Discuss in what ways such a structure is similar to and/or different than a list.

What are the differences between random hashed files and index files? Compare and contrast both these non-sequential file structure models.

Compare the two non-sequential file structure models: the random (hashed) file and the index file. What advantages does the first one have over the second and what advantages does the second have over the first? What would be your criteria for choosing one over the other for different applications?
