Backwards Analysis
Consider the following scheme to solve the sorting problem: given n numbers to be sorted, after the ith of n (1 ≤ i ≤ n), we will make sure that we have i of input numbers in a sorted list. Clearly these i sorted numbers will partition the ranks of the remaining n− i unsorted numbers into i + 1 intervals. The (i + 1)th step consists of choosing one of the n − i unsorted numbers uniformly at ran...
متن کاملPulling backwards
extinguished by the transfer. But the extent of the transformation is not yet clear. “It’s possible that what we are doing is turning everything into an oocyte,” says Gurdon. But he believes that oct4 expression is a good sign that the cells are at least headed toward becoming stem cells. Stem cell characteristics may develop only through sequential inductive events. But the optimists are hopin...
متن کاملBackwards Phonology
This paper constitutes an investigation into the generative capabilities of two-level phonology with respect to unilevel generative phonological rules. Proponents of two-level phonology have claimed, but not demonstrated, that two-level rules and grammars of twolevel rules are reversible and that grammars ofnnilevel rules are not. This paper makes "reversibility" explicit and demonstrates by me...
متن کاملBackwards Context Approximation
Context analysis calculates which components of arguments to functions may be evaluated eagerly without introducing non-termination. An amount of evaluation recommended by context analysis is less than the amount of evaluation which will occur at run-time. We may similarly derive contexts which are greater than the amount of run-time evaluation and hence determine which components of an express...
متن کاملDebugging Backwards in Time
By recording every state change in the run of a program, it is possible to present the programmer every bit of information that might be desired. Essentially, it becomes possible to debug the program by going “backwards in time,” vastly simplifying the process of debugging. An implementation of this idea, the “Omniscient Debugger,” is used to demonstrate its viability and has been used successf...
