Detailed Description
Market-model evolution description.
This class stores:
- 1.
- evolutionTimes = the times defining the rates that are to be evolved,
- 2.
- rateTimes = the times at which the rates need to be known,
- 3.
- relevanceRates = which rates need to be known at each time.
This class is really just a tuple of evolution and rate times;
- *
- there will be n+1 rate times expressing payment and reset times of forward rates.
- *
- there will be any number of evolution times.
- *
- we also store which part of the rates are relevant for pricing via relevance rates. The important part for the i-th step will then range from relevanceRates[i].first to relevanceRates[i].second. Default values for relevance rates will be 0 and n.
- *
