System Dynamics Explained: Understanding the delayed effects of birth rate changes

About the Series This series of articles is inspired and informed by Limits to Growth and its subsequent editions. In it, we will explore systems dynamics questions, and use Machinations models to answer them. Our conclusions so far In the last article, we used our model to understand why developed, post-industrial populations can decline: The model …

System Dynamics Explained: Understanding what causes rapid population growth

About the Series This series of articles is inspired and informed by Limits to Growth and its subsequent editions. In it, we will explore systems dynamics questions, and use Machinations models to answer them. This time, the question relates to the human population: What exactly has caused the surge in population over the last several centuries? …

Beyond Averages: How Monte Carlo Simulation Reveals the True Risks of Venture Capital Investing

The Danger of Averages One of the core and intractable challenges when simulating an uncertain future is the problem of quantisation: when an all-or-nothing outcome is distilled into an average that distorts the true meaning of the data. Though it’s often easier to say “Investing in this asset has an average return of 110%”, most …

Webinar: Why the “Lucky Catch” event in Merge Mansion is unbeatable

Understanding the Event and Showcasing the Problem Using Monte Carlo simulation powered by Machinations, I was able to determine that Merge Mansion’s original Lucky Catch event is unfinishable. Having played Merge Mansion quite avidly for over a year, I had plenty of opportunities to try out the seasonal Lucky Catch event, which is regarded rather …

How to Manage Complexity in Machinations

In the realm of game development and systems design, the ability to transform complex ideas into prototypes and simulations empowers designers to test their assumptions, refine design ideas, identify potential issues, and allows designers to assess the balance of game systems. Prototypes and simulations also serve as effective communication tools among the development team and …
