matcutest_select#

matcutest_select(options): matcutest_select selects the problems in MatCUTEst that satisfy given criteria.

problem_names = matcutest_select(options) returns the names of selected problems from MatCUTEst that satisfy the criteria in options as a cell array problem_names. More details about MatCUTEst can be found in the official website: <matcutest>.

options is a struct with the following fields:

ptype: the type of the problems to be selected. It should be a string or char consisting of any combination of 'u' (unconstrained), 'b' (bound constrained), 'l' (linearly constrained), and 'n' (nonlinearly constrained), such as 'b', 'ul', 'ubn'. Default is 'ubln'.

mindim: the minimum dimension of the problems to be selected. Default is 1.

maxdim: the maximum dimension of the problems to be selected. Default is Inf.

minb: the minimum number of bound constraints of the problems to be selected. Default is 0.

maxb: the maximum number of bound constraints of the problems to be selected. Default is Inf.

minlcon: the minimum number of linear constraints of the problems to be selected. Default is 0.

maxlcon: the maximum number of linear constraints of the problems to be selected. Default is Inf.

minnlcon: the minimum number of nonlinear constraints of the problems to be selected. Default is 0.

maxnlcon: the maximum number of nonlinear constraints of the problems to be selected. Default is Inf.

mincon: the minimum number of linear and nonlinear constraints of the problems to be selected. Default is 0.

maxcon: the maximum number of linear and nonlinear constraints of the problems to be selected. Default is Inf.

excludelist: the list of problems to be excluded. Default is not to exclude any problem.

Two things to note:

MatCUTEst is only available in Linux.
There is a file config.txt in the same directory as this function. This file can be used to set the option test_feasibility_problems. Details about this option can be found in the comments in the config.txt file.
