Three Approaches to Constructing Universal Functions for Literal Classes

Key Points

• To explore three different methods for constructing universal functions related to literal classes.
• Examined three approaches: definition-based, classical construction using Hamming code, and modified gradient method.
• Estimated cardinality for the domains of the constructed universal functions.
• Provided estimates for the cardinality of the domains of the new universal functions.
• Validated the effectiveness of the Hamming code approach for constructing these functions.
