Complete Deduction Rules -- Some Thoughts
Complete Deduction Rules: A Reevaluation of the Approach
Introduction
In the pursuit of creating a comprehensive system for integer arithmetic, I embarked on an exercise to develop a "complete" set of operations, also known as deduction rules. These rules aimed to enable users to perform "everything they could want" with addition, multiplication, and inequalities. The implementation of these rules was based on the standard axioms for an ordered ring. However, after engaging in discussions with Brian and others, and reflecting on the experience, I have come to the realization that this approach may not be the most effective.
The List of Deduction Rules
The list of deduction rules is currently available on a branch called complete_draft
. Upon reviewing the list, I counted a total of 54 rules. While this may seem like a manageable number, the actual implementation of these rules reveals a more complex picture.
Illustrating the Complexity of Deduction Rules
To better understand the intricacies of these rules, I provided a few simple deductions in a separate document called "arithmeticdeductions.md". One of the examples demonstrates that if x > y
and c
is negative, then c*y > c*x
. This seemingly straightforward deduction required 57 lines of implementation. The basic idea behind this deduction is that if c
is negative, then (-c)
is positive, and we have a deduction rule that states multiplying by a positive number leaves an inequality unchanged.
Lessons Learned
The experience of implementing these deduction rules has taught me a valuable lesson: building everything up from the most basic deduction rules is not an efficient approach in practice. The complexity of the rules and the resulting implementation can be overwhelming. Therefore, I suggest shipping the system with a bare minimum of deduction rules and allowing users to implement additional rules as custom.
The Value of a Complete Set of Deduction Rules
While the approach of building a complete set of deduction rules may not be the most practical, it is still valuable to have such a set available. This is because a complete set of deduction rules provides a foundation for understanding the underlying mathematics and can serve as a reference for users who want to implement custom rules.
Conclusion
In conclusion, while the exercise of creating a complete set of deduction rules was enlightening, it has also led me to reevaluate the approach. I believe that shipping the system with a bare minimum of deduction rules and allowing users to implement custom rules is a more efficient and practical approach. However, the complete set of deduction rules remains available for users who want to explore the underlying mathematics.
Future Directions
In the future, I plan to focus on implementing a more streamlined and efficient approach to deduction rules. This will involve identifying the most essential rules and providing users with a flexible framework for implementing custom rules. By doing so, we can create a system that is both powerful and user-friendly.
The Importance of User-Centered Design
As we move forward with the development of the system, it is essential to prioritize user-centered design. This means creating a system that is intuitive, easy to use, and meets the needs of our users. By doing so, we can ensure that our system is widely adopted and provides value to our users.
The Role of Community Involvement
Community involvement is crucial in the development of the system. By engaging with users, gathering feedback, and incorporating their suggestions, we can create a system that is truly user-centric. I encourage users to share their thoughts, ideas, and feedback with us, and we will do our best to incorporate them into the system.
Conclusion
In conclusion, the exercise of creating a complete set of deduction rules has been a valuable learning experience. While the approach may not be the most practical, it has provided us with a deeper understanding of the underlying mathematics and has led us to reevaluate our approach. I believe that shipping the system with a bare minimum of deduction rules and allowing users to implement custom rules is a more efficient and practical approach. However, the complete set of deduction rules remains available for users who want to explore the underlying mathematics.
