Function Documentation

auto sequant::opt::detail::footprint_counter(has_index_extent auto &&ixex)

Cost function returning the storage footprint (element count) of a single tensor: the product of the extents of its indices.

Used to apply a per-intermediate memory-footprint penalty in single-term optimization (see OptimizeOptions::footprint_weight). A scalar (no indices) contributes zero.

Parameters:

ixex – Invocable mapping an Index to its extent.

Returns:

A callable (result) -> double yielding the element count of the result tensor.
