Write a function, quickest_concat, that takes in a string and a list of words as arguments. The function should return the minimum number of words needed to build the string by concatenating words of the list.
You may use words of the list as many times as needed.
If it is impossible to construct the string, return -1.
def quickest_concat(s, words):
memo = {}
result = _quickest_concat(s, words, memo)
if result == float('inf'):
return -1
else:
return result
def _quickest_concat(s, words, memo):
if not s:
return 0
if s in memo:
return memo[s]
result = float('inf')
for w in words:
if s.startswith(w):
current = 1 + _quickest_concat(s[len(w):], words, memo)
result = min(result, current)
memo[s] = result
return result
To be more specific, I don't understand the purposes of memo, float('inf'), and min(), etc, in this function.
Answers
memo = {}
result = _quickest_concat(s, words, memo)
if result == float('inf'):
return -1
else:
return result
The quickest_concat function is the main function that takes in a string s and a list of words words. It initializes a dictionary memo to store previously computed results for optimization. It then calls the helper function _quickest_concat to calculate the minimum number of words needed to build the string s from the list of words.
def _quickest_concat(s, words, memo):
if not s:
return 0
if s in memo:
return memo[s]
result = float('inf')
for w in words:
if s.startswith(w):
current = 1 + _quickest_concat(s[len(w):], words, memo)
result = min(result, current)
memo[s] = result
return result
The _quickest_concat function is a recursive helper function that performs the actual computation. It takes the string s, the list of words words, and the memo dictionary as arguments.
The base case if not s: checks if the string s is empty. If it is, it means we have successfully built the entire string, so we return 0 (no additional words needed).
The next condition if s in memo: checks if the result for the current string s has already been computed and stored in the memo dictionary. If it is, we simply return the precomputed result, avoiding redundant computations.
If the current string s is not in the memo dictionary, we initialize the result variable with a large value float('inf'), representing infinity. This value will be updated as we find smaller values in subsequent iterations.
We iterate through each word w in the list of words. If the string s starts with the word w, it means we can concatenate w with the remaining part of the string.
We recursively call _quickest_concat on the remaining part of the string s[len(w):] and add 1 to the result since we have used one word.
We update the result variable with the minimum value between the current result and the newly computed current value. This ensures that we keep track of the smallest number of words needed to construct the string s.
Finally, we store the result in the memo dictionary for future reference and return the result.
(In Summary) The quickest_concat function takes in a string and a list of words and calculates the minimum number of words needed to construct the string by concatenating words from the list. The code uses recursion, memoization, and comparison with float('inf') and min() to efficiently find the solution while avoiding unnecessary computations.
The use of "memo", "float('inf')", and "min()" in the provided code is to optimize the computation by storing intermediate results, handling special cases, and finding the minimum value respectively.
What is the purpose of "memo", "float('inf')", and "min()" in the given code?In the provided code, the variable "memo" is used as a memoization dictionary to store previously computed results. It helps avoid redundant computations and improves the efficiency of the function. By checking if a specific string "s" exists in the "memo" dictionary, the code determines whether the result for that string has already been computed and can be retrieved directly.
The value "float('inf')" is used as an initial value for the variable "result". It represents infinity and is used as a placeholder to compare and find the minimum number of words needed to construct the string. By setting the initial value to infinity, the code ensures that the first calculated result will be smaller and correctly updated.
The "min()" function is used to compare and find the minimum value among multiple calculated results. In each iteration of the loop, the variable "current" stores the number of words needed to construct the remaining part of the string after removing the matched prefix.
The "min()" function helps update the "result" variable with the minimum value obtained so far, ensuring that the function returns the minimum number of words required to build the string.
By utilizing memoization, setting an initial placeholder value, and finding the minimum value, the code optimizes the computation and provides the minimum number of words needed to construct the given string from the provided list of words.

List six characteristics you would typically find
in each block of a 3D mine planning
block model.
Answers
Answer:
Explanation:
In a 3D mine planning block model, six characteristics typically found in each block are:
Block Coordinates: Each block in the model is assigned specific coordinates that define its position in the three-dimensional space. These coordinates help locate and identify the block within the mine planning model.
Block Dimensions: The size and shape of each block are specified in terms of its length, width, and height. These dimensions determine the volume of the block and are essential for calculating its physical properties and resource estimates.
Geological Attributes: Each block is assigned geological attributes such as rock type, mineral content, grade, or other relevant geological information. These attributes help characterize the composition and quality of the material within the block.
Geotechnical Properties: Geotechnical properties include characteristics related to the stability and behavior of the block, such as rock strength, structural features, and stability indicators. These properties are important for mine planning, designing appropriate mining methods, and ensuring safety.
Resource Estimates: Each block may have estimates of various resources, such as mineral reserves, ore tonnage, or grade. These estimates are based on geological data, drilling information, and resource modeling techniques. Resource estimates assist in determining the economic viability and potential value of the mine.
Mining Parameters: Mining parameters specific to each block include factors like mining method, extraction sequence, dilution, and recovery rates. These parameters influence the extraction and production planning for the block, optimizing resource utilization and maximizing operational efficiency.
These characteristics help define the properties, geological context, and operational considerations associated with each block in a 3D mine planning block model. They form the basis for decision-making in mine planning, production scheduling, and resource management.

(10 points) For EM algorithm for GMM, please show how to use Bayes rule to drive \( \tau_{k}^{i} \) in closed-form expression.
Answers
The closed-form expression for \( \tau_{k}^{i} \) in the EM algorithm for GMM is derived using Bayes rule, representing the probability that observation \( x_{i} \) belongs to the kth component. By dividing the likelihood and prior by the sum of all such terms, we arrive at the desired expression.
In EM algorithm for GMM, Bayes rule can be used to derive the closed-form expression for \( \tau_{k}^{i} \).
The expression is as follows:$$\tau_{k}^{i} = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$where, \(x_{i}\) is the ith observation, \(\theta_{k}\) represents the parameters of the kth component, \(p_{k}(x_{i}|\theta_{k})\) represents the probability of \(x_{i}\) belonging to the kth component, and \(\pi_{k}\) is the mixing proportion of the kth component.
To derive this expression using Bayes rule, we can use the following steps:1. Using Bayes rule, we can write the posterior probability of the kth component as:$$p_{k}(\theta_{k}|x_{i}) = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$2.
Since we are interested in the probability that the ith observation belongs to the kth component, we can simplify the above expression as:$$p_{k}(x_{i}|\theta_{k})\pi_{k} = \tau_{k}^{i}p_{k}(\theta_{k}|x_{i})\sum_{j=1}^{K}\tau_{j}^{i}p_{j}(x_{i}|\theta_{j})$$3. Dividing both sides of the above equation by \(p_{i}(x_{i})\), we get:$$\tau_{k}^{i} = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$This is the closed-form expression for \( \tau_{k}^{i} \) that we were looking for.
