Hi, All!
When constraints declared, it is meaning, that each constraint must be
ensure. Is it possible to specify how at least constraints enough ? Or to
use "exists" semantic? For example:

s.t. some_st{j in Objects}: exists {i in Resources}
x[i,j]*intensity[i,j]>=objectsCount[j];

Here I got error about invalid type "near exists".  How to fix this ? Help,
please !
