Make the library suitable for fast state-of-the-art optimization:

Gradient-Matrix product
Hessian-Vector product

API Features

Populating an existing vector instead of creating a new one, when computing the gradient
Allow specifying any IEnumerable/IList instead of requiring arrays.

- API BREAK The IntPower class has been renamed. It is not called ConstPower. In addition we also have TermPower.
- Division operator
- User defined n-ary functions, in addition to unary and binary functions. Huge thanks to davidanthoff for the patch.
- Evaluating gradients using a subset of the variables. Used for parameterized functions having "constant" parameters in addition to the actual function argument.
- Power terms can now have terms in the exponent, in addition to constants

Updated Release: 0.3 (Apr 03, 2011)

alexshtf — Sun, 03 Apr 2011 20:10:19 GMT

Changes:

Added the paradigm of term compilation. Compilation creates efficient representation of a term that allows quick evaluation/gradient computation
Compiled terms are differentiated with reverse-mode AD algorithm. It allows linear-time gradient computation (as opposed to quadratic worst-case time in the previous implementation)
Added samples
- HelloAutodiff sample with basic demo
- AdvancedHelloAutodiff demonstrates compiled terms
- Netwon-Raphson demo demonstrates solving an equation using the Newton-Raphson method and AutoDiff.
Bug fixes + stability improvements

Release plans

Manually differentiated functions support. The user provides a primitive function that evaluates its value and gradient. Then he/she can compose more complex functions using the provided function, and the library will be able to automatically differentiate and evaluate it.
Performance enhancements
