• Symbolic ↔ Neural: Bridge operations for knowledge integration
• Distributed ↔ Network: Multi-agent coordination and sharing

🚀 Usage Example

from ggml_tensor_kernel import GGMLTensorKernel, TensorOperationType
from moses_evolutionary_search import MOSESEvolutionarySearch
from psystem_membrane_architecture import PSystemMembraneArchitecture

# Create enhanced tensor kernel with prime factorization
kernel = GGMLTensorKernel("cognitive_agent")
persona = kernel.create_tensor("persona_state", "persona", "cognitive_traits")

# Evolutionary optimization
moses = MOSESEvolutionarySearch("evolution_agent")
best_patterns = moses.evolve(generations=10)

# Frame problem resolution
psystem = PSystemMembraneArchitecture("membrane_agent") 
context_membrane = psystem.create_context_membrane({
    "frame_constraints": ["core_concepts"],
    "change_scope": ["working_memory"]
})
