Read the equation
Divides input size by output size. A value above one indicates a smaller output. The ratio describes size only; recoverability and distortion require separate checks.
Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
Read CR as the quantity being defined or updated by this relation.
Forms a ratio or division. A zero denominator needs an explicit exclusion or handling rule.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.

1. Compression Ratio:
CR = \frac{\text{input size}}{\text{output size}}
2. Format Cost:
FC = \sum w_j\cdot \text{format}_j
3. Cost:
\text{Cost}_6 = a_6(1/CR) + b_6 FC
