Top Think Tanks Reminder of the rules: You enroll or sign on or start following 3 think tanks High quality, reputable ones, not Joe Blow’s Ideas Shop One must be US based and one must be based outside the US At least one of them must be deal with issues or come from a perspective that is not part of your normal sources of information, not ideas that you normally hear, ways of looking at the world that make you a “bit uncomfortable.” I do not mean “go sign up for extremist” think tanks. I mean something like this. You like Brookings because it’s a kind of traditional liberal perspective and focuses mostly on public “cures” to problems, as opposed to private sector initiatives. Fine, sign up for Brookings – then then sign up for Rand Corporation, too – to get a more private sector view of how to solve problems. Pick areas of expertise within your three choices that are of value from a community perspective, e.g. issues that affect entire communities as communities, not just as “collections of individuals. For example, school policy of course des affect individual students – but the policies are implemented at the state and community level. Simply put – stretch your thinking by topic and by the kind of think tank you follow. Where to find a think tank https://thebestschools.org/features/most-influential-think-tanks/
This site gives you a list of the top 50 think tanks. It’s a good place to start. I like to consult the University of Pennsylvania’s “Think Tanks and Civil Societies Program.” They provide de: //www.brookings.edu/
Brookings Institute is usually ranked as the #1 think tank in the U.S. and as one of the five think tanks with the greatest global influence, often ranked #1 in that category as well. Brookin: //www.heritage.org/
Heritage Foundation focuses on public policy “based on the principles of free enterprise, limited government, individual freedom, traditional American values, and a strong national defense.” : //www.cato.org/mission
Cato Institute focuses on public policy, and its aim is “…to originate, disseminate and increase understanding of public policies based on principles of individual liberty, limited government: //www.hrw.org/
Note: Human Rights Watch focuses on civil liberties and human rights worldwide. Their work is truly global in scale and they bring scholarship to bear on every aspect of human rights. Today, for example, they offer commentary on worker safety in the U.S., how the jewelry industry fuels human rights violations, Trumps actions and comments since the election, the effects of US “remain in Mexico” policy on children and families, infringements on journalism in China, rebel violence in Central African Republic, and the inequalities in availability of COVID-19 vaccines. Perspective – traditional liberalism; global www.csis.org
The Center for Strategic & International Studies (CSIS) focuses on international affairs. Its daily brief The Evening is great going to bed reading – not in the sense of “it’s boring,” but in: “CSIS’s purpose is to define the future of national security. We are guided by a distinct set of values – non-partisanship [they mean that], independent thought, innovative thinking, cross-disciplinary scholarship, integrity and professionalism, and talent development.” A modest agenda. Their definition of national security is well beyond “military strategy” and includes issues like global health, climate change, and human rights and the have programs with a regional focus as well. They DO have a strong focus on defense strategy. It is the overarching concern within which climate change, food security, poverty, and the African program are critical issues. Perspectives – traditional conservatism, US but with a strong global focus as well. www.jointcenter.org
The Black Institute is an action oriented think tank that is “… a Black-led policy and organizing institution dedicated to solving local problems and addressing the concerns of Black families: education, economic fairness, environmental justice, and immigration reform. You have to click on the menu button (upper right of banner) and ten on research and publications to see the full range of issues TBI addresses. These are well-developed and documented policy pieces with a strong focus on community. Perspective – independent, national (but includes immigration) https://aipi.asu.edu/

Write your solutions in this sheet below the problem statement. Mark clearly your solutions by corresponding letters A, B, C, D and separate visually each solution from the other ones by empty space or by a line. Use the other side of the sheet or ask for an additional blank sheeet if necessary. Each problem 1. – 4. is worth 0 – 4 points, each answer to a particular question A, B, C, D contributes at most 1 point to the total. 1. Four algorithms process a square matrix M of size nn. The indices of rows and columns of M start with 1. Each of the algorithms processes all matrix elements. Determine the asymptotic complexity of each algorithm.A. Algorithm A processes each element of M in time proportional to log(nn).B. Algorithm B processes each element in the row r in time k∙r, where k is a positive constant.C. Algorithm C processes each element at position [r][c] (r and c are row and column indices, respectively) in time k∙r∙c, where k is a positive constant.D. Algorithm D processes each element in constant time. However, before processing the element, the algorithm checks the value of each element in the row in which the processed element is located. Each check takes constant time to complete. 2. Insert sort processes an array A with an even number of values, array length is N. The array contains elements of only two values, 10 and 20. The first value in the array is 10 and the values in the array strictly alternate: 10, 20, 10, 20, 10, etc.A. Determine how many comparisons between two element values are performed when the length of the array is 8: 10 20 10 20 10 20 10 20 B. Determine how many comparisons between two element values are performed when the last element with value 10 is being inserted to its final position in array A. Solve the problem for the general value of N ≥ 4. C. Write a function f(N) which returns the total number of comparisons made during the sort of array A. Suppose N  ≥  4. Explain how did you derive f(N). D. Decide to which complexity class belongs f(N). The available classes are (1), (log N), (N), (N ∙ log N), (N2). 3. AVL tree T is in the picture. The four particular subtrees with roots in D, E, F, G are shown schematically and the value given in the subtrees represents the depth of the subtree. The depth is the number of edges on the path from the subtree root to the deepest node in the subtree.A. T is depicted immediately after a new key (not depicted) was inserted into the tree. To complete correctly the insert operation, a rotation hast to be applied in T. Draw the shape of T after this rotation and determine the type of the rotation (L, R, LR or RL). B. Insert keys 10, 30, 20, 50, 40, in this order, into an originally empty AVL tree, using Insert operation. Draw the resulting AVL tree and determine the number and the type (L, R, LR, RL) of each rotation used in the process.C. Delete the key 10 from the AVL tree built in C. Which rotation, if any, was applied in the deletion process?D. Suppose that an AVL tree contains n2 keys and that another n keys are inserted, one by one, into the tree using the Insert operation. Use the asymptotic notation (O//) to specify the maximum number of simple (L or R) rotations which are performed during the whole process. Explain your reasoning. 4. A binary heap is given in the picture.A. Determine all possible integer values of element Z in the heap.B. Substitute Z by its smallest possible value (calculated in the answer to question A) .Next, use the Insert operation to insert values 55, 45, 35 into the heap, in the given order. Draw the resulting heap.C. Apply twice operation ExtractMin to the heap obtained in B. Draw the resulting heap.D. Suppose that a binary heap H contains exactly 2n leaves. Operation ExtractMin is applied n times on H. What is the asymptotic complexity of the whole process? Explain your reasoning.
