Optimization Test Functions and Datasets.
Optimization Test Problems. The functions listed below are some of the common functions and datasets used for testing optimization algorithms. They are grouped according to similarities in their significant physical properties and shapes. Each page contains information about the corresponding function or dataset, as well as MATLAB and R implementations.
Mathematical optimization - Wikipedia.
Simplex vertices are ordered by their values, with 1 having the lowest fx best value. Mathematical optimization alternatively spelled optimisation or mathematical programming is the selection of a best element, with regard to some criterion, from some set of available alternatives.

Optimize Options Using the GNU Compiler Collection GCC.
Perform interprocedural constant propagation.This optimization analyzes the program to determine when values passedto functions are constants and then optimizes accordingly.This optimization can substantially increase performanceif the application has constants passed to functions.This flag is enabled by default at -O2, -Os and -O3 It is also enabled by -fprofile-use and -fauto-profile. Perform function cloning to make interprocedural constant propagation stronger.When enabled, interprocedural constant propagation performs function cloningwhen externally visible function can be called with constant arguments.Because this optimization can create multiple copies of functions it, may significantly increase code size see -param ipa-cp-unit-growth value This flag is enabled by default at -O3 It is also enabled by -fprofile-use and -fauto-profile. When enabled, perform interprocedural bitwise constantpropagation. This flag is enabled by default at -O2 andby -fprofile-use and -fauto-profile It requires that -fipa-cp is enabled. When enabled, perform interprocedural propagation of valueranges. This flag is enabled by default at -O2. It requiresthat -fipa-cp is enabled. Perform Identical Code Folding for functions and read-only variables.The optimization reduces code size and may disturb unwind stacks by replacinga function by equivalent one with a different name. The optimization worksmore effectively with link-time optimization enabled.
optimization Definition, Techniques, Facts Britannica.
Other important classes of optimization problems not covered in this article include stochastic programming, in which the objective function or the constraints depend on random variables, so that the optimum is found in some expected, or probabilistic, sense; network optimization, which involves optimization of some property of a flow through a network, such as the maximization of the amount of material that can be transported between two given locations in the network; and combinatorial optimization, in which the solution must be found among a finite but very large set of possible values, such as the many possible ways to assign 20 manufacturing plants to 20 locations.
