Dynamic Cycle

The Markov chain hypothesis is the hypothesis discussed in stochastic interactions, and has several applications. This strategy is always coordinated with future situations whose whereabouts cannot be known with certainty, so the community tries to carry out exercises with future directions full of vulnerabilities. Hypotheses are numerical ways of dealing with competitive planning situations and the struggles between different interests. This hypothesis is designed to examine the dynamic cycle of various serious states and includes at least two interests. In this situation, the information obtained from the voting results is then assessed for its legitimacy and quality by using the SPSS program. The consequence of counting with Markov chain's S Noodle items reduces the share of the entire industry by 5.8%, while the fun noodle items expands a portion of the entire industry by 41%, the side effect of the game hypothesis being specific. namely X1 with probability 0.5, X2 with probability 0.5 and X3 with probability 3.16. Meanwhile, to limit misfortune, Indomie consolidates three systems, namely Y1 with likelihood - 0.1, Y2 with likelihood 0.5 and Y3 with likelihood 1.

We look forwards and backwards in the multi-allelic neutral exchangeable Cannings model with fixed population size and nonoverlapping generations. The Markov chain X is studied which describes the allelic composition of the population forward in time. A duality relation (inversion formula) between the transition matrix of X and an appropriate backward matrix is discussed. The probabilities of the backward matrix are explicitly expressed in terms of the offspring distribution, complementing the work of Gladstien (1978). The results are applied to fundamental multi-allelic Cannings models, among them the Moran model, the Wright-Fisher model, the Kimura model, and the Karlin and McGregor model. As a side effect, number theoretical sieve formulae occur in these examples.

The aim of this paper is to obtain the optimal strategies of two competitive players using Game Theorem and to make future predictions of games using Markov Chains involving the EPL. All the teams that have participated since 2005/2006 EPL season to EPL 2019/2020 season were considered and the method of proportion of wins was used to select five best teams. Linear programming was employed to select the optimal strategies, while the predictions for seasons 2020/2021 to 2023/2024 are obtained by Markov chain method. The results obtained revealed that Man U is the optimal strategy for Player A, and that Player A has to choose Man U to maximize his profit, meanwhile, Chelsea is the optimal strategy for Player B and he has to choose Chelsea to minimize his loss. The findings of the results also revealed that for Man U or Chelsea to win their home games, it will depend on their current home winning against the team they are playing with.

Blockchain has been an emerging technology, which comprises lots of fields such as distributed systems and Internet of Things (IoT). As is well known, blockchain is the underlying technology of bitcoin, whose initial motivation is derived from economic incentives. Therefore, lots of components of blockchain (e.g., consensus mechanism) can be constructed toward the view of game theory. In this paper, we highlight the combination of game theory and blockchain, including rational smart contracts, game theoretic attacks, and rational mining strategies. When put differently, the rational parties, who manage to maximize their utilities, involved in blockchain chose their strategies according to the economic incentives. Consequently, we focus on the influence of rational parties with respect to building blocks. More specifically, we investigate the research progress from the aspects of smart contract, rational attacks, and consensus mechanism, respectively. Finally, we present some future directions based on the brief survey with respect to game theory and blockchain.

<p><em>Terminal Klari that located in Kabupaten Karawang has a function</em> <em>as a temporary stop place for public vehicles to raise and lower passengers. PO Bus with Klari – Purwokerto route is the object of the research. The large number of PO busses on this route causes loyalty of the passenger is decline. These observations were made on 6 PO Busses with Klari – Purwokerto route and with 6 attributes, there are price, service, facilities, ease of getting information, easy of getting tickets, and the travel time. The objective of the research is to determine the competitive strategies based on the analysis of the bus brand switching by bus passengers with Klari – Purwokerto route. This research utilizes a Markov chain, game theory, and short route models. The results of processing and analysis using Markov chain, obtained that the market share reached steady state in the 11th period with a yield of 16.09% for Dedy Jaya, 29.35% for Murni Jaya, 25.13% for Sinar Jaya, 7.97% for Pahala Kencana, 10.69% for DMI, and 10.77% for Dieng Indah. From game theory method the results of the game there are several alternative strategies for DMI Buses, such as improving the means of promotion and communication so the passengers can get information with easily about Bus DMI. The alternative route from the short route model is Klari Terminal - Tol Kranci / Pejagan - Bumi Ayu - Purwokerto, with a total distance of 304.7 km.</em></p>

Market Share

Supermarket dan minimarket adalah tempat dimana orang-orang sering membeli produk shampoo yang mereka inginkan. Metode Markov Chain digunakan untuk melihat transisi dari masyarakat dalam mengubah pilihan produk shampoo dan tempat perbelanjaan selama dua periode ke depan. Produk shampoo yang menjadi objek penelitian adalah Clear, Lifebuoy, dan Sunsilk yang merupakan tiga dari sekian banyak produk shampoo yang dikeluarkan oleh perusahaan multinasional Unilever. Metode Game Theory diterapkan untuk membandingkan keunggulan dari Transmart dan Carrefour yang beroperasi di Karawang, walaupun masih dibawah satu naungan, tetapi manajemennya berbeda sehingga service-nya pun pasti berbeda. Selain supermarket, persaingan minimarket Alfamart dan Indomaret juga dianalisis dengan menggunakan metode Game Theory. Hasil pengolahan data pada metode Markov Chain menunjukkan bahwa probabilitas transisi dan market share untuk dua periode ke depan dari ketiga produk tersebut adalah sebesar 31,45% untuk shampoo Clear, 39% untuk shampoo Lifebuoy, dan 29,55% untuk shampoo Sunsilk. Lalu, probabilitas transisi dan market share untuk dua periode ke depan dari tempat perbelajaan (supermarket) terhadap ketiga produk tersebut adalah sebesar 38,94% untuk Hypermart, 19,87% untuk Giant, dan 41,18% untuk Transmart. Sedangkan probabilitas transisi dan market share untuk dua periode ke depan dari tempat perbelajaan (minimarket) terhadap ketiga produk tersebut adalah sebesar 47,61% untuk Alfamart, 43,06% untuk Indomaret, dan 9,33% untuk Toko Kelentong. Selanjutnya, pengolahan data pada Game Theory menunjukkan bahwa saddle point dalam persaingan antara Transmart dan Carrefour adalah 12 untuk kualitas pelayanan Carrefour dan fasilitas untuk Transmart. Sedangkan saddle point dalam persaingan antara Alfamart dan Indomaret adalah 4 untuk fasilitas Indomaret dan pelayanan untuk Alfamart.
