[#206] In LPP, degeneracy occurs in ____________ stages.
Correct Answer

(B) Two

Explanation

Solution: In LPP, degeneracy occurs in two stages. Degeneracy in a linear programming problem is said to occur when a basic feasible solution contains a smaller number of non-zero variables than the number of independent constraints when values of some basic variables are zero and the Replacement ratio is same.

[#207] Every LPP is associated with another LPP is called ______________.
Correct Answer

(B) Dual

Explanation

Solution: Every LPP called the primal is associated with another LPP called dual. Either of the problems is primal with the other one as dual.

[#208] In a matrix of transition probability, the element aij where i=j is a.
Correct Answer

(C) Retention

Explanation

Solution: In a matrix of transition probability, the element aij where i=j is a retention.

[#209] In Markov analysis, state probabilities must.
Correct Answer

(A) Sum to one

Explanation

Solution: In Markov analysis, state probabilities must sum to one. Markov assumptions: (1) the probabilities of moving from a state to all others sum to one, (2) the probabilities apply to all system participants, and (3) the probabilities are constant over time.

[#210] State transition probabilities in the Markov chain should.
Correct Answer

(A) Sum to 1
