The constraints of the dual problem forbid two dual variables to take values that correspond to two incompatible tuples. Without these constraints, one dual variable may take the value corresponding to the tuple x = 1 , y = 2 {\displaystyle x=1,y=2} while another dual variable takes the value corresponding to y = 3 , z = 1 {\displaystyle y=3,z ...
Some brinkmates involve tsumes that needs two condition to be met in order to defend (e.g. two mates are threatened). The defending side could give a check and simultaneously meet one condition (which is only possible in shogi games and brinkmate problems involving two kings), and then satisfy the other condition.
In mathematical analysis, the alternating series test is the method used to show that an alternating series is convergent when its terms (1) decrease in absolute value, and (2) approach zero in the limit.
Under certain conditions (called "constraint qualification"), if a problem is polynomial-time solvable, then it has strong duality (in the sense of Lagrangian duality). It is an open question whether the opposite direction also holds, that is, if strong duality implies polynomial-time solvability.
For events in B, two conditions must be met: the probability of B is one and the relative magnitudes of the probabilities must be preserved. The former is required by the axioms of probability , and the latter stems from the fact that the new probability measure has to be the analog of P in which the probability of B is one - and every event ...

Informally, Slater's condition states that the feasible region must have an interior point (see technical details below). Slater's condition is a specific example of a constraint qualification. [2] In particular, if Slater's condition holds for the primal problem, then the duality gap is 0, and if the dual value is finite then it is attained.
