VSEngineering Contradiction Analysis

1Adaptability or versatility

If Centralized Training and Decentralized Execution (CTDE) is used to enable collaborative behavior in MARL, then agents can learn to work together, but the optimization of agent operations becomes insufficient when a large number of agents are involved

Engineering Contradiction:
Improvecollaborative behaviorVSAvoidoptimization efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces the classical computing system used in CTDE with a quantum computing system. The quantum main unit utilizes quantum mechanical principles (quantum bits, quantum parallelism, quantum entanglement) to process environmental information and determine action policies for multiple agent units, achieving superior optimization efficiency compared to classical computational approaches

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the computational parameters from classical bits to quantum bits (qubits), enabling the system to process multiple states simultaneously through quantum superposition. This parameter change allows the quantum main unit to evaluate numerous action policies in parallel, significantly improving optimization efficiency for large numbers of agents

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the number of agent units is increased to handle complex tasks, then collaborative performance can be improved, but the computational complexity increases making optimization difficult

Engineering Contradiction:
Improvecollaborative performanceVSAvoidcomputational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the system into a quantum main unit for centralized computation and multiple agent units for decentralized execution. This segmentation allows the computational complexity to be managed by separating the complex policy determination (performed by the quantum main unit) from the simpler environmental interaction (performed by individual agent units)

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The quantum main unit acts as an intermediary between the environment and the agent units. It receives environmental information from all agent units, processes this information using quantum computing to determine optimal action policies, and then provides these policies back to the respective agent units, thereby managing the computational complexity of coordinating multiple agents

Inventive Principle:
Principle #24Intermediary (Mediator)
