Introduction

**Course Review: Quantitative Model Checking on Coursera** In an era where technology influences our daily lives significantly, the need for dependable software systems has never been greater. Elements like Embedded Systems, Cyber-Physical Systems, Communication Protocols, and Transportation Systems critically rely on robust software to prevent catastrophic failures and costly errors. If you're interested in ensuring that these systems operate smoothly, then the "Quantitative Model Checking" course on Coursera could be your key to mastering this impactful field. ### Course Overview "Quantitative Model Checking for Markov Chains" offers an in-depth exploration of model checking methodologies particularly centered on Markov Chains. This course delves into various probabilistic models and the techniques necessary for ensuring their reliability. The well-structured syllabus ranges from foundational concepts to advanced topics, effectively guiding participants—from beginners to seasoned professionals—through the essential components of quantitative model checking. ### Syllabus Breakdown **Module 1: Computational Tree Logic** The course starts with Labeled Transition Systems (LTS), establishing a foundation as it introduces Computational Tree Logic (CTL). The exploration of model checking algorithms here is vital, as they facilitate computation of satisfaction sets for specific CTL formulas. The beauty of this module lies in its structured teaching approach, making complex ideas accessible to learners. **Discrete Time Markov Chains** In this module, you'll enhance your understanding by integrating probabilities into transition systems. By examining the memoryless property and time-homogeneity of Discrete Time Markov Chains (DTMCs), you'll be equipped to explore state classification and the implications of limiting and stationary distributions—skills crucial for analyzing probabilistic systems. **Probabilistic Computational Tree Logic** The introduction of Probabilistic Computational Tree Logic (PCTL) takes your learning a step further. This module dives into the syntax and semantics of PCTL while tackling the algorithms required to validate various PCTL formulas. It also sheds light on the complexity of PCTL model checking—the depth of the content prepares you for real-world applications. **Continuous Time Markov Chains** Transitioning from discrete to continuous, this module investigates Continuous Time Markov Chains (CTMCs) and emphasizes real-time modeling. Through steady-state analyses and transient probability computations using uniformisation, the course prepares you for practical scenarios where time is of the essence. **Continuous Stochastic Logic** Concluding the curriculum, the final module introduces Continuous Stochastic Logic (CSL) and its applicability in model checking. The focus on time-bounded until operators illustrates how techniques like uniformisation can be used—providing you with the toolkit to handle real-world time-dependent systems. ### Why You Should Enroll 1. **Practical Relevance**: With technology infiltrating almost every industry, the skills acquired from this course are not just academic; they have a direct impact on improving software reliability in critical systems. 2. **Structured Learning**: The clarity and organization of modules help to build knowledge progressively.

Syllabus

Module 1: Computational Tree Logic

We introduce Labeled Transition Systems (LTS), the syntax and semantics of Computational Tree Logic (CTL) and discuss the model checking algorithms that are necessary to compute the satisfaction set for specific CTL formulas.

Discrete Time Markov Chains

We enhance transition systems by discrete time and add probabilities to transitions to model probabilistic choices. We discuss important properties of DTMCs, such as the memoryless property and time-homogeneity. State classification can be used to determine the existence of the limiting and / or stationary distribution.

Probabilistic Computational Tree Logic

We discuss the syntax and semantics of Probabilistic Computational Tree logic and check out the model checking algorithms that are necessary to decide the validity of different kinds of PCTL formulas. We shortly discuss the complexity of PCTL model checking.

Continuous Time Markov Chains

We enhance Discrete-Time Markov Chains with real time and discuss how the resulting modelling formalism evolves over time. We compute the steady-state for different kinds of CMTCs and discuss how the transient probabilities can be efficiently computed using a method called uniformisation.

Continuous Stochastic Logic

We introduce the syntax and semantics of Continuous Stochastic Logic and describe how the different kinds of CSL formulas can be model checked. Especially, model checking the time bounded until operator requires applying the concept of uniformisation, which we have discussed in the previous module.
