This study proposes a novel and efficient surrogate model for performing truss analysis based on graph theory and deep learning algorithms, which is applicable for various truss topologies with different load scenarios without requiring retraining as other Deep Learning (DL)-based counterparts.

An algorithm finding the shortest path joining two given vertices in an extended graph has been studied in other papers. In this paper, we show that the algorithm presented in doesn’t work for the extended graphs in. We define the other extended graph, called an extended weighted graph, such that a similar algorithm works for it.

The present paper employs an Particle Swarm Optimization (PSO) Improved via Genetic Algorithm (IPSO) based on Support Vector Machines (SVM) for efficient prediction of various stock indices. The main difference between PSO and IPSO is shown in a graph. Different indicators from the technical analysis field of study are used as input features.

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).

Functions are "the central objects of investigation" in most fields of modern mathematics. There are many ways to describe or represent a function. Some functions may be defined by a formula or algorithm that tells how to compute the output for a given input. Others are given by a picture, called the graph of the function.

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.
