ao 0.2.6

CRAN release: 2023-03-31

• Added package logo and created package website (https://loelschlaeger.de/ao/) with the {pkgdown} package. No code changes.

ao 0.2.5

CRAN release: 2023-01-23

• Updated code to the new optimizeR version 0.3.0, which renamed changed some input and output names.

• In particular, in ao(), renamed input optimizer -> base_optimizer.

ao 0.2.4

CRAN release: 2022-12-04

• Updated code to the new optimizeR version 0.2.0, which renamed some functions.

ao 0.2.3

CRAN release: 2022-09-02

• Fixed bugs when having ... arguments for ao().

ao 0.2.2

CRAN release: 2022-08-24

• Removed the set_f() interface. The optimization problem is now specified directly in ao().

• The output format of ao() has been changed, see the documentation of ao().

• Arbitrary optimizer can now be specified in ao() as an optimizer object via the framework from the {optimizeR} package.

CRAN release: 2022-01-04

• The Himmelblau’s function is included as an example.

ao 0.2.0

• ao() now returns the sequence of estimates in the different iterations as a data frame.

• ao() now is able to plot the sequence of estimates during estimation.

• Argument groups in ao() now is called partition and sequence is replaced by iterations.

• New function set_f() for specification of the optimization problem. Parameter constraints can now be imposed on the target function.

• New helper functions is_number(), try_silent(), timed() and euclidean().
