4D Knapsack (Time-Travel Variant)

You are a temporal smuggler operating in a 4-dimensional hypergrid $(x, y, z, t)$. You have a storage unit with capacity $V$ and a temporal flux limit of $\Delta T$.

Given a list of items, where each item $i$ has:

  • Volume: $v_i$
  • Value: $p_i$
  • Temporal Instability: $t_i$
  • Existential Risk: $r_i$ (float 0.0 - 1.0)

Find the maximum value you can store such that the total Volume $\le V$ and the total Instability does not collapse the local universe ($\sum t_i \le \Delta T$).

Note: Since 2032, O(N^4) solutions are automatically rejected by the compiler. You must optimize for quantum-coherent states using the @memoize_4d decorator.

Input: Hypercube Size [100, 100, 100, 5000]
Your complexity: O(N^4)
Required complexity: O(N * log(Time))
Hint: Have you considered folding space-time to reduce iteration?
