Weak Metrics on Configurations of a P System
نویسندگان
چکیده
The evolution of a P system generates a tree of computation potentially infinite where it is very difficult to set the degree of closeness between two configurations. The problem is specially hard if we want to quantify that proximity in order to make useful comparisons. In this paper we propose some weak metrics on configurations of a P system with a fixed structure of membranes and briefly discuss their advantages and drawbacks.

متن کاملBuilding a Comprehensive Conceptual Framework for Power Systems Resilience Metrics
Recently, the frequency and severity of natural and man-made disasters (extreme events), which have a high-impact low-frequency (HILF) property, are increased. These disasters can lead to extensive outages, damages, and costs in electric power systems. A power system must be built with “resilience” against disasters, which means its ability to withstand disasters efficiently while ensuring the ...
متن کاملMetrics and Evaluation Tools for Patient Engagement in Healthcare Organization- and System-Level Decision-Making: A Systematic Review
Background Patient, public, consumer, and community (P2C2) engagement in organization-, community-, and systemlevel healthcare decision-making is increasing globally, but its formal evaluation remains challenging. To define a taxonomy of possible P2C2 engagement metrics and compare existing evaluation tools against this taxonomy, we conducted a systematic review. Methods A broad search strate...
