Superfast Algorithms and the Halting Problem in Geometric Algebra
  A new type of algorithms is presented that combine the advantages of quantum and classical ones. Those combined advantages along with aspects of Geometric Algebra that open possibilities unavailable to both of these computations are exploited to obtain database search and number factoring algorithms that are faster than the quantum ones, and even to create a ''pseudoalgorithm'' that can perform noncomputational tasks.
