The transition of copper cable technology to fiber optic is very triggering the development of technology where data can be transmitted quickly and accurately. This cable change can be seen everywhere. This cable is an expensive cable. If it is not installed optimally, it will cost enormously. This excess cost can be used to other things to support performance rather than for excess cable that should be minimized. Determining how much cable use at the time of installation is difficult if done manually. Prim's algorithm can optimize by calculating the minimum spanning tree on branches used for fiber optic cable installation. This algorithm can be used to shorten the time to a destination by making all the points interconnected according to the points listed. Use of this method helps save the cost of fiber optic construction.

Smart school is a technology-based school concept used in the teaching and learning process in the classroom. The use of educational technology includes an integrated system that assists the educational community in carrying out their respective functions with the aim of developing the potential of students. The use of technology in the field of education is expected to help and facilitate students and schools in conducting learning so that technology is able to facilitate and solve problems in learning. In building smart schools, it is also necessary to design technology developed in technology. The concept of network development that will be used is to use the Top-Down method and the topology used is to use ring topology and star topology. With the development of smart schools, it is expected that education using technology will continue to develop.

We study the problem of constructing minimum power-$p$ Euclidean $k$-Steiner trees in the plane. The problem is to find a tree of minimum cost spanning a set of given terminals where, as opposed to the minimum spanning tree problem, at most $k$ additional nodes (Steiner points) may be introduced anywhere in the plane. The cost of an edge is its length to the power of $p$ (where $p\geq 1$), and the cost of a network is the sum of all edge costs. We propose two heuristics: a ``beaded" minimum spanning tree heuristic; and a heuristic which alternates between minimum spanning tree construction and a local fixed topology minimisation procedure for locating the Steiner points. We show that the performance ratio $\kappa$ of the beaded-MST heuristic satisfies $\sqrt{3}^{p-1}(1+2^{1-p})\leq \kappa\leq 3(2^{p-1})$. We then provide two mixed-integer nonlinear programming formulations for the problem, and extend several important geometric properties into valid inequalities. Finally, we combine the valid inequalities with warm-starting and preprocessing to obtain computational improvements for the $p=2$ case.

Effective resistance to intellectual property (IP) piracy, overproduction and reverse engineering are becoming more and more necessary in the integrated circuit (IC) supply chain. To protect the hardware, the obfuscation methodology hides the original function by adding a large number of redundant states. However, existing hardware obfuscation approaches have hardware overhead and efficiency of obfuscation limitations. This paper proposed a novel methodology for IP security using the minimum spanning tree finite state machine (MST-FSM) obfuscation. In the minimum spanning tree (MST) algorithm, the Hamming distance defines the cost of obfuscated states. The Kruskal algorithm optimizes the connection relationship of obfuscated states by computing the Hamming distance of the MST-FSM. The proposed MST-FSM is automatically generated and embedded in the hardware IP with the self-building program. Finally, the MST-FSM is applied on the itc99 benchmark circuits and encryption standard IP cores. Compared with other state-of-the-arts, the obfuscation potency is improved by 3.57%, and the average hardware cost is decreased by about 6.01%.

Jaringan fiber optic merupakan suatu jaringan kabel yang dapat mentransmisikan sinyal cahaya dari suatu lokasi ke lokasi lainnya dengan kecepatan tinggi. Dibandingkan dengan kabel lainnya, kabel fiber optic ini cenderung lebih tahan lama, lebih cepat dalam mengirim sinyal cahaya. Namun demikian, harganya relatif lebih mahal dari kabel yang lainnya. Oleh karena itu diperlukan cara untuk meminimalisir jaringan pada jaringan fiber optic, salah satu caranya dapat menggunakan minimum spanning tree. Pada saat ini, di Universitas Tanjungpura sudah menggunakan jaringan fiber optic untuk akses internet dari satu unit ke unit yang lainnya. Dalam penelitian ini dibahas mengenai penerapan beberapa algoritma sebagai alternatif untuk mendapatkan MST pada jaringan fiber optic di Universitas Tanjungpura. Hasil penelitian menunjukkan jika menggunakan algoritma Kruskal, algoritma Prim, dan algoritma Sollin diperoleh  panjang jaringan kabel yaitu 4310 meter sedangkan sebelum menggunakan MST diperoleh panjang kabel sebesar 8765 meter. Selanjutnya, untuk jaringan fiber optic yang terbentuk dari algoritma Kruskal dan algoritma Prim menghasilkan jaringan yang sama, namun untuk algoritma Sollin berbeda. Perbedaannya terletak pada akses dari Fakultas Hukum ke Rumah Sakit Untan dan dari Fakultas Ekonomi dan Bisnis ke Fakultas Kedokteran. Kata Kunci : algoritma Kruskal, algoritma Prim, algoritma Sollin

The paper investigates two-stage stochastic minimum spanning tree games with perishable goods. The cooperative behaviour of the players is defined. At each stage, all players jointly take action to construct a network with a cost matrix. At the second stage, a particular player may leave the game, and the probability of this leaving depends on the cooperative behaviour of all players at the first stage. At each stage game, the total cost of the spanning tree is calculated to include the sum of the costs of the contained edges and the cost of the loss of perishable goods expended on that edge of the spanning tree. The characteristic functions in the game are considered, and the dynamic Shapley values are modified. The time consistency of the dynamic Shapley values is studied.

Consider a complete graph $K_n$ where the edges have costs given by independent random variables, each distributed uniformly between 0 and 1. The cost of the minimum spanning tree in this graph is a random variable which has been the subject of much study. This note considers the large deviation probability of this random variable. Previous work has shown that the log-probability of deviation by $\varepsilon$ is $-\Omega(n)$, and that for the log-probability of $Z$ exceeding $\zeta(3)$ this bound is correct; $\log {\rm Pr}[Z \geq \zeta(3) + \varepsilon] = -\Theta(n)$. The purpose of this note is to provide a simple proof that the scaling of the lower tail is also linear, $\log {\rm Pr}[Z \leq \zeta(3) - \varepsilon] = -\Theta(n)$.

In last decade, application developers attained improved performances by merely employing the machines based on higher-clocked processors. However, in 2003 multi-core processors emerged and eradicated the old processor manufacturing technology based on increasing processor’s clock frequencies. After emergence of new parallel processor architectures, serial applications must be re-engineered into parallel versions to exploit the computing power of the existing hardware. In this paper, we present an efficient parallel implementation of minimum spanning tree algorithm to take advantage of the computing power of multi-core machines. Computer network routing, civil infrastructure planning and cluster analysis are typically use-cases of spanning tree problem. The experimental results show that the proposed algorithm is scalable for different machine and graph sizes. The methodology is simple and can easily be implemented using different shared-memory parallel programming models.
