چکیده
Breadth-First Search. For a graph like the one in Figure 2.3, we can generally figure out the distance between two nodes by eyeballing the picture; but for graphs that are even a bit more complicated, we need some kind of a systematic method to determine distances. The most natural way to do this — and also the most e cient way to calculate distances for a large network dataset using a computer — is the way you would probably do it if you Breadth-First Search: Layers

I Given n students and n colleges, each with preferences over the other. Can we find a stable matching? I Stability: Don’t want to match c with s and c′ with s′ if c and s′ would prefer to switch to being matched with each other. I Yes! Propose and Reject Algorithm.

متن کامل"Hey #311, Come Clean My Street!": A Spatio-temporal Sentiment Analysis of Twitter Data and 311 Civil Complaints
1 Abstract— Twitter data has been applied to address a wide range of applications (e.g., political election prediction and disease tracking); however, no studies have been conducted to explore the interactions and potential relationships between twitter data and social events available from government entities. In this paper, we introduce a novel approach to investigate the spatio-temporal rela...
متن کاملMulti-layer Clustering Topology Design in Densely Deployed Wireless Sensor Network using Evolutionary Algorithms
Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
