Branch:

default

Phase:

public

Message:

Slightly modify the interface of Circulation and Preflow (#266)
in order to synchronize them to the interface of NetworkSimplex?.

Circulation:

• The "delta" notation is replaced by "supply".
• lowerCapMap(), upperCapMap() are renamed to lowerMap() and upperMap().
• Value is renamed to Flow.

Preflow:

• Value is renamed to Flow.

File:

• lemon/preflow.h (modified) (17 diffs)
