“…An advantage of this model is its ability to simplify a complex phenomenon using the simple rules so that its behavior can be predicted well. It is also possible to predict its emergent property of the corresponding complex system as a whole by applying this model (Alatas et al., 2017).…”

“…There has been renewed interest in the application of an agent‐based model as it successfully simulates various complex behaviors such as economy (Farmer & Foley, 2009), energy (Rai & Henry, 2016), social (Alatas et al., 2017; Helbing, 2013), and traffic (Sugihakim & Alatas, 2016). An agent‐based model is defined as a computational model to simulate and describe a complex phenomenon numerically using autonomous agents.…”

Flood caused by overflowing water from river has become a major issue in Southeast Asia, as it has caused economic losses and deaths. Therefore, the present work aims to propose an alternative approach for morphometric analysis of the Ciliwung River Upper Stream (CRU) without the geographic information system technique use for flood prevention strategy application. For the river network simulation, an agent‐based model having several rules in terms of agent, landscaping, and action was adopted. In addition, the river morphometric characteristics, namely, river network, river order, bifurcation ratio, length‐order ratio, fractal dimension, watershed density, and river capacity were estimated. It was found that the proposed technique was able to estimate the river morphometric characteristics of CRU. CRU has the river order, bifurcation ratio, length‐order ratio, fractal dimension, watershed density, and river capacity of 4, 1.1–2.5, 0.6–1.1, 1.84, 0.01 km km–2, and 1,404,060 L, respectively. It was also identified four suitable locations to build artificial dams for flood prevention strategy by employing the presently proposed technique. The proposed artificial dams with heights ranging from 10 m to 25 m demonstrated to have capability to prevent flood in the capital city of Jakarta, Indonesia.

“…On one side, there are classical binary state models [ 7 ] that are often subject to exact analytical treatment, although their assumptions and formulation can be seen as oversimplified, especially from the social science point of view. On the other hand, it is also possible to move towards a very general approach of agent-based models [ 8 , 9 , 10 , 11 ], equipping individuals with large vectors of attributes, applying detailed, very complex rules and, last but not least, taking into account multidimensional structure of interactions.…”

We analyze a nonlinear q-voter model with stochastic noise, interpreted in the social context as independence, on a duplex network. The size of the lobby q (i.e., the pressure group) is a crucial parameter that changes the behavior of the system. The q-voter model has been applied on multiplex networks, and it has been shown that the character of the phase transition depends on the number of levels in the multiplex network as well as on the value of q. The primary aim of this study is to examine phase transition character in the case when on each level of the network the lobby size is different, resulting in two parameters q1 and q2. In a system of a duplex clique (i.e., two fully overlapped complete graphs) we find evidence of successive phase transitions when a continuous phase transition is followed by a discontinuous one or two consecutive discontinuous phase transitions appear, depending on the parameter. When analyzing this system, we even encounter mixed-order (or hybrid) phase transition. The observation of successive phase transitions is a new quantity in binary state opinion formation models and we show that our analytical considerations are fully supported by Monte-Carlo simulations.

“…Basing on this criteria we can deal with continuous (plane-like) [5,12,33,34] or discrete geometry. The later may be divided into additional subgroups, with regular lattices [21-23, 25, 35] or complex networks [8,19,[36][37][38][39][40][41].…”

In this paper Nowak-Szamrej-Latané model is reconsidered. This computerised model of opinion formation bases on Latané theory of social impact. We modify this model to allow for multi (more than two) opinions. With computer simulations we show that in the modified model the signatures of order/disorder phase transition are still observed. The transition may be observed in the average fraction of actors sharing the i-th opinion, its variation and also average number of clusters of actors with the same opinion and the average size of the largest cluster of actors sharing the same opinion. Also an influence of model control parameters on simulation results is shortly reviewed. For a homogeneous society with identical actors' supportiveness and persuasiveness the critical social temperature TC decreases with an increase of available opinions K from TC = 6.1 (K = 2) via 4.7, 4.1 to TC = 3.6 for K = 3, 4, 5, respectively.
