• CGSS: Complex Networks

    Behind complex networks, there are networks that describe the interaction between components. Basics A network is  a set of nodes interconnected by a set of links. The adjacency matrix [latex]A[/latex] of a network is the matrix which contains non-zero element [latex]A_{ij}[/latex] if there exists an edge between node [latex]i[/latex] and [latex]j[/latex]. The resulting graph is […]

  • CGSS: Introduction to Mechanism Design

    Game Theory outlines the problem of the free-rider dilemma in public goods. In order to overcome the tragedy of the commons mechanism design was proposed. The basic idea is to define the the payoff and actions in order to drive people towards a preferred behaviour. Public Goods Game From the mechanism design perspective  two individuals  […]

  • CGSS: Introduction to Game Theory

    A fundamental problem is over-usage. Usually, nobody wants over-usage to occur. However, on an individual level companies want to maximise their profit while they neglect the social cost. The problem is also known as the Tragedy of the commons which is based on the free-rider dilemma. A game is defined by three components: players, actions, […]

  • CGSS: Introduction

    Complexity and Global Systems Science (CGSS) will cover Game Theory and mechanism design, complex network, socio-physics, and critical thinking essays regarding the topic. Complexity science is related to systems that are made up of thousands of units, whereas global systems describe large systems. Systemic instabilities are of a major interest and need to be understood. […]
