**Witness Algorithm**Presented by Alp Sardağ**Witness Algorithm**• Like other algorithms, start with a set of vectors, V*t-1={0(t-1),..., M(t-1)}. • Sayfa 81 deki ilk formül • The output of the algorithm will be a set of vectors, V*t-1={0(t-1),..., N(t-1)}.**Witness Algorithm**• Let Qat the set of vectors representing PLWC value function, for performing action a at time t and performing optimally there after. • Qat = {0a(t),..., Na(t)} • There will be a separate Qat for each action a. • Sayfa 81 10 a kadar olan formüller**Witness Algorithm**• The algorithm first constructs the Qat sets • Then constructs the desired V*t set of vectors. • In constructing Qat set, the algorithm incrementally build up. • Note that: • Sayfa 81 son formül**Constructing Qat**• Begin with an empty set Qat, choose any belief point and construct the vector using: • Formula 10 buraya kopyalanacak. • Determine if there exist a belief state * (like Sondik’s): • Sayfa 82 formüllerin ilk iki satırı kopyala. • Once the new vector found, it is added to the list of vectors.**Constructing Qat**• How the algorithm finds the new belief point? • Sayfa 83 ün sonu ve 84 ün 4 formülü kopyalanacak.**Constructing Qat**• Sayfa 85 teki LP kopyalanacak.**Constructing Qat**• The algorithm for constructing Qat is as follows: • Sayfa 85 pseudocode copy paste edilecek.**Witness Algorithm Reduction Phase**• Once all Qat sets found for each action a, then combine them to form the set V*t that is the optimal value function. • The algorithm uses reduction phase of Monahan’s algorithm. • Monahan’s reduction LP si kopyalanacak.
