Function Documentation

template<typename IdxToSize, typename = std::enable_if_t<std::is_invocable_r_v<size_t, IdxToSize, const Index&>>>
ExprPtr sequant::opt::optimize(ExprPtr const &expr, IdxToSize const &idx2size, bool reorder_sum)
Parameters:

  • expr – Expression to be optimized.

  • idxsz – An invocable object that maps an Index object to size.

  • reorder_sum – If true, the summands are reordered so that terms with common sub-expressions appear closer to each other.

Returns:

Optimized expression for lower evaluation cost.
