We will have our weekly meetings with Ravi on Tuesday mornings at 9.30 in my office. The general topic is algorithmic problems appearing in the science of design: http://www.cs.virginia.edu/~sullivan/sodsis.html Ravi's wiki about this topic is at: http://koods1.ccs.neu.edu/ Choose the traversal wiki. Ravi: please can you remind us of the password. It used to be K@rl? Topics for Tuesday: Strengthening the FPT results in our crosscut expressiveness paper. Revisions to the paper suggested by referees: complexity of selector interference: s1 & s2 is non-empty. Kathy's and Shriram's pointcut language in their model checking work (see talk on Wednesday). How does an aspect influence the running time of a base program? The base program has running-time O(n^2). With the aspect the running time is O(n log(n)) or O(n^3). How can we prove such statements? Any other algorithmic problems that came up in Pengcheng's, Theo's or Jeff's research. -- Karl
