Stopping conditions.

#	Stopping condition	Explanation
1	Reaching the border of tumor where it is cured approximately (feasible region).	Algorithm stops when becomes zero or less for the best generated cell and an approximate acceptable solution is generated.
2	Reaching a fixed number of chemotherapy repetitions.	Algorithm stops after a predetermined number of runs and converting the cancer cells to their corresponding healthy ones.
3	Reaching a fixed value for and getting near to the border of tumor.	Algorithm stops when it is in a predetermined special distance of feasible region and a predetermined and result.
4	Reaching a percentage of improvement in or tumor size.	Algorithm stops when has a predetermined percentage of improvement in comparison to its initial value.
