Provides several direct search optimization algorithms
based on the simplex method. The provided algorithms are direct
search algorithms, i.e.  algorithms which do not use the
derivative of the cost function. They are based on the update
of a simplex. The following algorithms are available: the fixed
shape simplex method of Spendley, Hext and Himsworth
(unconstrained optimization with a fixed shape simplex), the
variable shape simplex method of Nelder and Mead (unconstrained
optimization with a variable shape simplex made), and Box's
complex method (constrained optimization with a variable shape
simplex).

Provides several direct search optimization algorithms
based on the simplex method. The provided algorithms are direct
search algorithms, i.e. algorithms which do not use the
derivative of the cost function. They are based on the update
of a simplex, which is a set of k>=n+1 vertices, where each
vertex is associated with one point and one function value. The
following algorithms are available: Spendley, Hext and
Himsworth fixed size simplex method - unconstrained
optimization with a fixed sized simplex made of k=n+1
vertices). Nelder and Mead variable size simplex method -
unconstrained optimization with a variable sized simplex made
of k=n+1 vertices). Box complex method - constrained
optimization with a variable sized simplex made of an arbitrary
k number of vertices (k=2n is recommended by Box).

The aim of the neo2R is to provide simple and low level connectors
for querying neo4j graph databases (<https://neo4j.com/>).
The objects returned by the query functions are either lists or data.frames
with very few post-processing.
It allows fast processing of queries returning many records.
And it let the user handle post-processing according to the data model
and his needs.

Querying and Managing 'Neo4J' Databases in 'R'
person("Keith", "McNulty", email = "keith.mcnulty@gmail.com",
role = c("aut", "cre", "cph"))
Sends queries to a specified 'Neo4J' graph database, capturing results in a dataframe where appropriate.
Other useful functions for the importing and management of data on the 'Neo4J' server and basic local server admin.
