From uncertainty to resolution | Example: Piano keys | High time resolution, low frequency resolution | Good middle ground | Low time resolution, high frequency resolution

The problem instance data | Relation to best known and trivial solution | Relative deviation from best known solution | Run time

Covariant derivative | Examples

Creating a labeled array (tensor) | Performing calculations | Contraction | Diagonal subsetting | Outer product | Inner product | Mixed product: tensor multiplication w/ contractions and subsetting | Element-wise product | Kronecker product | Addition and Substraction | (Anti-)symmetrization | Unlabel a tensor
