Markov Algorithm vs Probability
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Markov Algorithm
This tool emulates a Markov Machine, a string rewriting system used in computer science. It helps students test and debug algorithms with grammar-like rules and a step-by-step execution log.
- Markov Machine emulator
- String rewriting system
- Grammar-like rule application
- Step-by-step debugging
- Execution log

Students of computer science are probably familiar with Markov algorithm. A string rewriting system that uses grammar-like rules to operate on strings of symbols. This application is a great Markov Machine emulator which can help you test your algorithms and debug it step-by-step using convenient execution log.

Probability
Read full descriptionHide full description
Probability Calculate the probability of conditional events or unconditional events. Conditional events Example: What is the probability of throwing one six with a dice in throw number two with the condition that throw one was a six. Unconditional events Example: What is the probability that it will be some six in two throws with a dice whether it is throw number one or two. Up to ten events can be linked together.

Verdict
The clearest difference is in-app purchases: Probability at none against Markov Algorithm's 3. Probability also leads on iOS requirement (9.0 vs 15.0). Markov Algorithm's advantage is update cadence (every 5 weeks vs every 18 months). On price, ads and device support there is nothing between them.
