Weighted graph We can add attributes to edges, We call the attributes weights; Then if we want the shortest travel distance between cities an appropriate weight would be the road mileage; If we are concerned with the dollar cost of a trip and went the cheapest trip then an appropriate weight for the edges would be the cost to travel between the cities.
This second edition of Data Structures and Algorithms in Java has been augmented to
make it easier for the reader and for instructors using it as a text in computer science
classes. Besides coverage of additional topics, we’ve added end-of-chapter questions,
experiments, and programming projects.
It’s convenient to describe a data structure in terms of the operations performed, rather than in terms of implementation details.
That means we should separate the concepts from particular implementations.
When a data structure is defined that way, it’s called an abstract data type (ADT).

For both groups we combined all the answers in which subjects gave the same confidence
assessment and calculated how often they were right. Good calibration means that the
fraction of correct answers should be about equal to the stated confidence level. For example,
on questions where subjects said they were 80 percent confident, they should be right about
80 percent of time. If subjects are well calibrated, then a graph of the percent correct against
the confidence levels should lie near a 45◦ line.
This topic reviews the basic mathematics required in this course: A justification for a mathematical framework, the ceiling and floor functions, L’Hôpital’s rule, logarithms, arithmetic and other polynomial series, geometric series, recurrence relations, weighted averages, combinations.
There are several improvements for bipartite network ﬂows . However they require the network to be unbalanced in order to substantially speed up the algorithms, i.e. either |U | |V | or |U | |V |, which is not the case in our context. The complexity of ﬁnding an optimal (minimum or maximum weight) matching might be reduced if the cost label is also a metric on the node set of the underlying graph. For example if the nodes of the graph are points in the plane and the cost label is the L1 (manhattan), L2 (Euclidean) or L∞ metric...
Given a connected, undirected graph, a spanning tree of that graph is a subgraph that is a tree and connects all the vertices together. A single graph can have many different spanning trees. We can also assign a weight to each edge, which is a number representing how unfavorable it is, and use this to assign a weight to a spanning tree by computing the sum of the weights of the edges in that spanning tree.
We study random surfaces which arise as height functions of random perfect matchings (a.k.a. dimer conﬁgurations) on a weighted, bipartite, doubly periodic graph G embedded in the plane. We derive explicit formulas for the surface tension and local Gibbs measure probabilities of these models. The answers involve a certain plane algebraic curve, which is the spectral curve of the Kasteleyn operator of the graph. For example, the surface tension is the Legendre dual of the Ronkin function of the spectral curve.
