Figure 1: Search tree
1. Uninformed search algorithms (6 points)
Based on the search tree in Figure 1, provide the trace to find a path from the start node
S to a goal node T for the following three uninformed search algorithms. When a node
has multiple successors, use the left-to-right convention.
a. Depth first search (2 points)
b. Breadth first search (2 points)
c. Iterative deepening search (2 points)
We want to get an idea of how many tickets we have and what our issues are. Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.
Figure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT. Show all your working.(c) Implement your design using AND/OR/NOT logic gates and risingedgetriggered D-type Flip Flops. Your answer should include a circuitschematic.

- A controller is required for a home security alarm, providing the followingfunctionality. The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…arrow_forward4G+ Vo) % 1.1.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forward
