> > > Solve complex one and multi dimensional optimizations problems efficiently with our powerful optimization component. This component offers advanced algorithms covering local and global unidimensional optimization, local multidimensional optimization with or without constraints. We also include a method for solving liner programming prooblems known as the simplex method.

> > > New Self-Deploy By clicking the self-install package the EJB component will be automatically deployed onto a supported local EJB application server (see details).

> > > This suite includes the following features:

> > > - Local unidimensional optimization-finds global minima / maxima for continuous functions in one dimension
> > >   - Fast `low level' algorithms-use these algorithms when your primary concern is the speed and not the accuracy of the results. You will have to chose one bracketing algorithm and one locate algorithm (note, they are useful only in pairs). Also you will have to manually provide a lot of parameters (tolerance, maximum cycles etc) which can dramatically change the algorithm performance.
> > >     - Bracketing algortihms-these methods find an interval where at least one extrema of a continuous function exists
> > >     - Acceleration bracketing-this method can be used with any continuous functions
> > >     - Parabolic extrapolation bracketing-gives better results than acceleration bracketing for a large class of functions (functions that are locally parabolic about the extrema)
> > >     - Acceleration bracketing for derivable functions-requires derivatives to be known; it's slower than the general acceleration algorithm but also safer
> > >     - Locate algorithms-these methods converge to the extrema if the extrema is bracketed and the function under consideration is continuous
> > >     - Parabolic interpolation locate-very fast algorithm but with moderate accuracy
> > >     - Linear locate-slow algorithm but exhibits stable convergence
> > >     - Brent locate-medium speed with good accuracy. With a good balance of speed and accuracy, this algorithm is very efficent to use
> > >     - Cubic interpolation locate-very fast algorithm with reasonable accuracy; requires the derivatives to be known
> > >     - Brent method for derivable functions-medium speed; good accuracy; requires derivatives
> > >   - Accurate `high level' algorithms-these algorithms are easy to use and offer high accuracy but are also very slow compared with the `low level' algorithms above (1000 to 10000 times slower). Use these algorithms when you need reliable results. The probability for a `high level' algorithm to make a mistake is much less than that of `low level' algorithms.
