Given an improving variable, it is possible to create correcting variables heuristically.
If no improving variable can be found, the LP solution must be optimal.
These other variables are called correcting variables in the following, since they "correct" the changes the improving variable induces if used basic solution.
This means, given an improving variable, a totally new assignment based on this variable is created and the remaining variables are also added to the problem.
Additional, since every assignment contains |F|variables (compare constraint (6c)), adding one improving variable by adding |F|−1 others as well causes a certain inefficiency or redundancy.
Further and especially concerning fractional solutions within the linear relaxation, the surrounding variables may not allow to use the improving variable to its full extend, compared to the best possible usage.
For this purpose, some modifications of construction heuristics, e.g., some DSATUR variation[19, 28] suffice to create enough surrounding variables such that the improving variable can potentially have a value above zero in the next basic solution.
PHP 7 will also contain an improved variable syntax which is internally consistent and complete, resolving a long-standing issue in PHP, what will allow use of ->,,,, and :: operators with arbitrary meaningful left-hand-side expressions.
We applied bagging to improve variable selection, hence adapted the Bolasso.
Significant change noted after each stage, therefore weight loss stage did not significantly improve variable.
