This paper presents an optimal strategy for solving the 4 peg-7 color Mastermind MM(4,7) in the expected case (4.676) along with optimal strategies or upper bounds for other values. The program developed is using a depth-first branch and bound algorithm relying on tight upper bound, dynamic lower bound evaluation and guess equivalence to prune symmetric tree branches.

A 69-year old bed-bound woman presented with chest pain and diaphoresis. Diagnostic imaging led to the diagnosis of bilateral extensive pulmonary emboli extending into all segmental branches. Tissue plasminogen activator (tPA) was administered via 2 separate EKOS catheters. Repeat evaluation after 33 hours revealed improvement of right ventricular size and function. EKOS catheters are useful fo...

Many cell types, including fi broblasts and epithelial cells, move forward by forming an actin-rich membrane protrusion, called a lamellipodium, at the front of the cell. In the early 1990s, researchers thought that lamellipodial protrusion was driven by the polymerization of linear actin fi laments. In two JCB papers published in 1997 and 1999, however, Tatyana Svitkina and colleagues revealed...

The paper describes a hybrid approach for dynamic system modelling. This proposal is mainly based on a Least Squares algorithm and a Multi-Branch Genetic Programming (MB-GP) encoding. Having multiple branches representing an individual allows us to get simpler mathematical expressions, and therefore, reduces the computational evaluation time.
