“Induced” Eyes Suggest a Path to Retinal Repair

Anti-evolutionists have long cited the eye as evidence against evolution. The organ is so intricate and complex, they argue, that it could not exist but for the careful guidance of a grand designer. Indeed, even Darwin himself labored to explain how such complexity might be the product of natural selection. The presence of primitive eye-like structures in lower species and, ironically, the non-...

The path to DNA repair.

-The 1970-72 cancer mortality of Polish migrants to England and Wales is compared with the cancer mortality prevailing in England and Wales and in Poland. Small numbers limit the analyses to the most frequent cancer sites only. The main findings are: (a) Compared with mortality rates in both their country of birth and of adoption, Polish migrants displayed intermediate values for cancers of the...

Path-Based Program Repair

We propose a path-based approach to program repair for imperative programs. Our repair framework takes as input a faulty program, a logic specification that is refuted, and a hint where the fault may be located. An iterative abstraction refinement loop is then used to repair the program: in each iteration, the faulty program part is re-synthesized considering a symbolic counterexample, where th...

The Path repair algorithm

In this paper, we introduce a new solving algorithm for Constraint Satisfaction Problems: the path-repair algorithm. The two main points of that algorithm are: it makes use of a repair algorithm (local search) as a basis and it works on a partial instantiation in order to be able to use ltering techniques. Di erent versions are presented and rst experiments with both systematic and non systemat...
