1. This problem exercises the basic concepts of game playing, using tic-tac-toe (noughts and crosses) as an example. We define Xn as the number of rows, columns, or diagonals with exactly n Xs and no Os. Similarly, On is the number of rows, columns, or diagonals with just n Os. The utility function assigns +1 to any position with X3=1 and -1 to any position with 03-1. All other terminal positions have utility O. For nonterminal positions, we use a linear evaluation function defined as Eval(s)=3x2 (s) + X1(s)-(3 02 (s) + 01(s)). a. Approximately how many possible games of tic-tac-toe are there? b. Show the whole game tree starting from an empty board down to depth 2 (i.e., one X and one on the board), taking symmetry into account. c. Mark on your tree the evaluations of all the positions at depth 2. d. Using the minimax algorithm, mark on your tree the backed-up values for the positions at depths 1 and 0, and use those values to choose the best starting move.

Explain the key principles and concepts behind the Wilson approach in a nutshell.

. Below is a description of the business process of a hospital.After reading the business process below, provide an ERD showing the primary key, all attributes,relationships, and cardinalities as in the sample ERD.     When developing ERD, you must use a diagramming tool. Using an ERD tool is a part of diagramdrawing, so hand-drawn ERD will not be accepted. While various free ERD drawing tools areavailable on the web, some tools may require you to pay depending on the tool and the plan you select.You may refer to this list https://clickup.com/blog/erd-tools/ and select a tool you want. However, thetools you may select are not limited to the list in the link.Once you have completed your diagram, print it as a PDF file and submit it to CougarVIEW dropbox.If you need multiple pages to include all your tables, print it in multiple pages.Description of business processIn hospital, there are many departments like Orthopedic, Pathology, Emergency, Dental,Gynecology, Anesthetics, I.C.U.,…

Why not split down the overall design into several user perspectives when doing user research?

Summarize and cite related work by others; compare your methods and results with others’ work.

A thorough breakdown of the wait-and-see strategy is provided. What are the main disadvantages of this kind of interaction? Create a formula to determine the amount of time spent connected using this case study.

If you could perhaps provide three compelling reasons in behalf of the spiral model rather than the waterfall model, I would really appreciate it. Thank you.

Complete a crow’s foot Entity Relationship Diagram based off of the business rules that are listed below. Be sure your ERD fits the business rules that are described. Be sure to show appropriate cardinalities and relationship descriptions. Be sure to label your primary keys and foreign keys. Upload a screen print of your completed ERD image.   Business Rules: An urgent care clinic that tracks patient information in electronic format has the following business rules.   The doctor’s name, office number and phone extension are stored. A patient’s name, area code, phone number, email and balance they owe are tracked. A patient can have appointments with one or more doctors The appointment date and time are tracked for each and every appointment that a patient makes. A doctor can have appointments with zero or more patients. However, each appointment is made with only one doctor and one patient. If the patient shows for an appointment, it results in a visit with the specified doctor. A…

For each of the scenarios below please describe what would be the best design pattern to be used, explain the appropriateness and advantages of using that pattern, and draw a corresponding design diagram for that scenario including that pattern. Describe the participants and collaborations. Please respond to all of the above 4. There is a system configured to work with three pretzel stores: Pretzel Maker, Wetzel, and Auntie Anne's. They create similar yet custom-made pretzels, and the system needs to be independent from the way the pretzels are created. Each pretzel store uses its own ingredients (products), yet similar to the other stores. They each use their own kind of dough, cheese, and sauce.
