Most non-trivial pricing systems use some curves.

* term structures - usually means time-based curves

* swap curve - closely related to yield curve

* yield curve

* discount curve

* fwd curve

* dividend curve

* vol surface

* credit default curve (hazard rate)

Who don't use curves? Some pricing systems simply "adopt" bid/ask from the market with minimal validation. Perhaps good enough for mark-to-market, but not pre-trade. Simplistic (almost naive) pre-trade pricing algo gives up our independent thinking and makes our trading engine a blind slave.

A lot of the best bid/ask aren't _consistent_.

- consistent with historical data

- consistent with other parts of a curve. Outliers.

Therefore, chief challenges in curve-based pricing include

- selecting the most suitable analytical form - polynomial, exponential, piece-wise linear(?) ...

- outliers,

- curve-fitting,

- smoothness calculation,

- fitting cost calculation -- measures deviation from original points.
