◆ costcap_blocked

template<class T>

std::vector<cache::CacheBlockedPair> line::nc::NcCacheSolution< T >::costcap_blocked

Storage cost caps that block a promotion path, so that the exact recursion normalizes over MORE states than the cache can reach.

The port has no warning channel, so this is a FLAG, like SjnResult::capped: a non-empty vector means cross-check the answer with SolverLDES.

◆ costcap_method_switched

template<class T>

bool line::nc::NcCacheSolution< T >::costcap_method_switched = false

◆ missprob

template<class T>

std::vector<T> line::nc::NcCacheSolution< T >::missprob

(u) per-class miss and hit PROBABILITIES, missrate divided by the read class's arrival rate and its complement.

Carried beside the rate because getAvgCacheTable reports a probability and the two differ by a factor no consumer downstream can recover: the arrival rate is the Source's and is gone by the time the table is built. NaN for a class with no read stream, which is not a hit ratio of zero.
