class QPanda::OptBMTQAllocator
==============================

.. toctree::
	:hidden:

Subgraph Isomorphism based :ref:`Qubit <doxid-class_q_panda_1_1_qubit>` Allocator. This QAllocator is split into 3 phases: 1.Partitions the program into a number of smaller programs, and find all\* subgraph isomorphisms from the graph of that program to the coupling graph (architecture); 2.Dynamic programming that tests all combinations of subgraph isomorphisms, while estimating the cost of glueing themtogether; 3.Reconstructs the selected sequence of subgraph isomorphismsinto a program.
