You are replacing the whole object on each iteration, you just need to create it if it does not exists, otherwise you can replace the key.

QUESTION

To which Knapsack-problem variation does this problem correspond?

Asked 2022-Mar-19 at 17:06

Let us imagine that I have to fill my knapsack with items under constraints:

Each item has an associated weight wi and profit pi
With a maximum total weight Wmax

Knowing that:

There are categories of items and I have to choose exactly one item from each category
Of course, the aim is to choose items to maximise the sum of the profits

Example : Wmax=400 Books Books weights Books profits Food Food weights Food profits The Bible 500 25 Cheese 80 120 The little prince 150 5 Banana 250 200

Here, the best solution is (The little prince, Banana)

I have a similar problem and I'd like to find out the best way to code it but I can't figure out what version/ variation of the probleme this is, is it a known variation ?

...

ANSWER

Answered 2022-Mar-19 at 17:06

I’m not sure if there’s an existing variation that matches yours, but it’s easy to draw inference from the classical variant and solve this.

Classic variant has 2D dynamic programming (DP[N][W], where N and W are number of items and max weight).

In this variant, since we can only pick one of each category, you can use 3D DP like dp[i][w][j], which denotes the maximum value you can get from the first i items with weight w and j is a 0/1 int denoting whether an item from category number j has been selected or not.

I’ll leave the implementation, since the recursive relation is relatively simple and quite similar to the classic variant.

Azure Data Explorer (Kusto/KQL) Financial Asset Backtesting Trail Stop

Asked 2022-Mar-16 at 20:24

I have a data set of financial asset prices over time and I'd like to mimic a trail stop for back testing strategies against this data set.

Trail stops are a type of trade order supported by some online brokers that are used as a stop loss or profit protection when opening a position, a trail stop is placed to automatically stop loss when a price condition is met.

The trail stop order will follow an asset price as it increases, and stay at the max during the time the position is open, once the asset price falls below the trail stop max, the position will be closed by the broker.

In this case the trail stop is a percentage of asset price. i.e. asset price less 3%.

I've tried a number of approaches, including summarization and the scan operator, and can't seem to land on a working prototype.

Below is an example data table of an asset with price changes over time.

ANSWER

Answered 2022-Mar-16 at 20:24

Investopedia for a good explanation about trailing stop

Order by position & timestamp
Use prev() to identify the starting of a new position.
Use scan() to calculate running max of CallPremium (always goes up, resets for a new position).
Compare each CallPremium to the running max and check if trailing stop achieved.

QUESTION

Maximize the diff of elements of Two Arrays B[j] − A[i] where j > i

Asked 2022-Mar-13 at 23:34

This is not the max-profit algorithm, but a variation of it.

I have an array A, where A[i] corresponds to the price of computers in country A and time i. And B[i] corresponds to the price of computers in country B and time i.

All entries in each array are positive integers. I want to buy computers in country A at some time i and then sell them in country B at some later time j > i.

I need to maximize profit B[j] − A[i].

Example:

...

ANSWER

Answered 2022-Mar-13 at 23:34

In order to do that in O(n) time you can use the logic that very is similar to Kadane's algorithm for finding the maximum sum of a sub-array.

The overall idea is to track the minimum price previously encountered for country A.

And at each step of iteration, compare the profit that can be obtained by selling the computers at the current price B[i] (assuming that they were bought at a minimum price minA) with the maximum profit.

Minimum price for country A minA initialized with the first element in the array countryA[0]. And at each iteration step it's being compared with the value of element countryA[i - 1].

The best possible profit for each step will be countryB[i] - minA, where minA is the smallest value among countryA[0] ... countryA[i - 1].

The case when the given arrays are of different length or comprised of less than 2 elements represents the situation when the input data is incorrect, therefore IllegalArgumentException is thrown.

QUESTION

Redis storing and getting multiple records

Asked 2022-Mar-03 at 19:13

I'm quite new to redis and have a task at hand to optimize redis operations for a dashboard of a non-profit.

The scenario:

We have multiple cities (London, Rome,...)
We have 1000s of users in each city

We have a need to load users from a particular city, and at the moment it is stored by city ID. As you can imagine, this results in a massive document that needs to be re-cached on every small change to the user.

I want to change this methodology so users are stored in Redis in the following format: [cityID][userID]. So if I need to pull all users from london, I can just call IDFORLONDON?

Would this be the correct way to approach it? Is there a way to load only 10 users from IDFORLONDON? (for pagination). Or is my option to load all and then slice?

Thank you!

I'm gonna recommend you go with RedisJSON if you can. RedisJSON is a module that you can add to Redis to extend its capabilities—in this case adding JSON documents and a whole host of commands to read, write, and manipulate them.

...

ANSWER

Answered 2022-Feb-03 at 16:38

Conditional types, as originally implemented in microsoft/TypeScript#21316 are not always evaluated eagerly. If they depend on an as-yet-unspecified generic type parameter, like the M inside the body of the Refl definition, the compiler will generally defer evaluation of the conditional type. Note that the details about exactly when and where the compiler will evaluate a conditional type are not spelled out in any documentation, and they've been evolving over time with new releases of TypeScript, so I can't say anything with absolute certainty here. But the general situation is as I've described it.

You were expecting the compiler to look at M extends M ? true : false and eagerly reduce it to true so that your definition would be equivalent to type Refl = true, either inside the definition of Refl or inside the definition of Proof. Neither of these evaluations happen; they are deferred because in both cases M is an unspecified type parameter. So the compiler cannot be sure that Refl will be any narrower than the union true | false (also known as the boolean type), and thus is not known to satisfy the constraint for IsTrue.

So it isn't that M extends M ? true : false should ever actually evaluate to false (as far as I know it can't), but that the compiler fails to evaluate it at all in order to simplify it to true.

I don't see any GitHub issues about this specific circumstance, but there are many such issues which boil down to the compiler's inability to analyze conditional types that depend on an unresolved generic type parameter. For a relatively recent example, see microsoft/TypeScript#46795.

Note that the particular form M extends ... ? ... : ... where M is a plain generic type parameter is known as a distributive conditional type and so any unions in M would be broken into individual members before being evaluated. This doesn't affect whether Refl could ever be wider than true, but it can affect the output type:
