Discrete Mathematics Graph Theory

I searched everything I could. I couldn't find anything, only information about transport networks, but that's not it(?). Need help!! 1) Find a flow on a given graph whose values on vertical edges (with orientation from bottom to top) are, respectively, from left to right, 2, 3, 4 and 5, its values on any two horizontal edges are zero. 2) Find a function on the vertices of this graph whose gradient values on the inclined edges (with an orientation from bottom to top) are, respectively, from left to right, 3, 4 and 5, and the gradient value on some four horizontal edges is zero. 3) Draw a graph with the same passport, but not isomorphic to this one. Prove that the graphs are not isomorphic.

This graph

triangle, rectangle, slope, parallel

What else can I help you with?

Differences between finite math and discrete math?

Discrete Mathematics is the mathematical study of constructs that are not continuous. Addition over the set of integers is discrete as apposed to the continuous constructs of division over the set or real numbers. Topics included range over: Set theory, Combinatorics, Graph Theory, Probability, Number Theory, Numerical Analysis (Computer Science), Geometry, Topology, Game Theory (also called decision theory or utility theory), Information Theory, Logic, some forms of Algebra, Discrete Calculus, the study of Rings/Groups and Mappings.Finite Mathematics is a colloquial term used to describe a subset of discrete mathematics. Most commonly finite mathematics is a college bossiness course covering finite (not infinite) problems in probability theory, linear programming, basic concepts of matrices, and simple Calculus (of finite differences).The major difference in the two topics is that finite mathematics covers a limited scope of problems (business related) using only a small set of the discrete mathematic tools for domains and ranges that are finite. Discrete mathematics covers any possible problem that a mind can imagine, using a vast array of diverging techniques, for problems that potentially have infinite domains and/or ranges (sometimes the problems go beyond the basic confines of domains and ranges).


What is discrete structures?

Discrete structures refer to mathematical concepts that deal with distinct and separate objects rather than continuous quantities. This area of mathematics includes topics such as graph theory, combinatorics, logic, set theory, and algorithms, which are fundamental in computer science and information technology. Discrete structures are essential for understanding the underlying principles of data structures, databases, and programming languages. They provide the tools needed for analyzing and solving problems where discrete data is involved.

What graph is used to discrete data?

Any kind of graph can be used for discrete data.


How many nodes are in a family branch tree in graph theory?

In Mathematics and Computer Science, the graph theory is just the theory of graphs basically overall. It's basically the relationship between objects. The nodes are just lines that connects the graph. There are a total of six nodes in a family branch tree for a graph theory basically.


Definition of discrete structures?

Discrete structures are foundational material for computer science. By foundational we mean that relatively few computer scientists will be working primarily on discrete structures, but that many other areas of computer science require the ability to work with concepts from discrete structures. Discrete structures include important material from such areas as set theory, logic, graph theory, and combinatorics.


What is a discrete graph?

A graph composed of isolated points.


What is a graph made up of unconnected points?

It is Discrete Graph .


Is a linear graph considered to be a continuous graph?

It can be continuous or discrete.


Discrete and Continuous data is used in mathematics?

Yes it is. Discrete data is something that's set. Like say you were making a line graph about renting bikes. You can only rent whole bikes there is nothing in between. You shouldn't connect points on a line graph with discrete data but some cases can be argued. Continuous data is usually a measurement that could change like time.


Is a graph that has a finite or limited number or data points a discrete graph?

Yes, a graph that has a finite or limited number of data points is considered a discrete graph. Discrete graphs represent distinct, separate values rather than continuous data, which would be represented by a continuous graph. In a discrete graph, individual points are plotted, reflecting specific values without connecting lines between them.
