what is the term for general class of problems that involve optimising arrangements

e.g.

1 day ticket costs 3, 3 day ticket costs 5, and 5 day ticket costs 9

foo travels to bar city on days 1, 2, 5, 7, 9, 15, 16, 25

if foo travels on an even-numbered day, the tickets are discounted by 50%

help foo spend the least on tickets

constraint satisfaction problem or csp

theyre all reducible to sat then whack em into the sat solver. or mixed integer program solver

right so the problem that prompted me to ask that question is a bounded knapsack problem, meaning that i probably shouldn�t feel to bad about only partially solving it in 2 hours while being utterly oblivious to the concept

you always get the biggest goddamn weenies asking for dynamic program solns to csp or knapsack or subset sum poo poo

been learning java and so far this just seems like python with more pointless poo poo
like, for example:

Java code:

double[] values = new double[ArrayLen];

why do i need to tell it TWICE that it's a double array

# ? Nov 17, 2021 15:24

because its statically typed and they dont have hejlsberg or spj or like one of 10 other dudes so they cant implement the cool kids nice type system

		Fish carp = new Fish("Common Carp",2);
		Fish sunfish = new Fish("Ocean Sunfish", 500);
		Fish bluefish = new Fish("Bluefish", 7.9);
		Fish pike = new Fish("Northern Pike", 1);

		// create pond
		ArrayList<Fish> pond = new ArrayList<Fish>();
		// populate pond
		pond.add(carp);
		pond.add(sunfish);
		pond.add(bluefish);
		pond.add(pike);
		
		System.out.println("Total weight: " + totalFishWeight(pond));

I don't understand what the problem is here? Is it saying that the username and password are concatenated to a single string? Or you just don't like that they're being supplied as strings at all for some reason?

probably should have put some context. this was in the internal "solution to replace storing secrets in plaintext config" which pointed to using an API called from a library that has "step 1: login using secrets stored in config"

also note that instead of ArrayList<Fish> pond = new ArrayList<Fish>(); you can omit the type in the constructor call: ArrayList<Fish> pond = new ArrayList<>();

This is actually kinda hosed up because you might think you can put a cat into your animals array, but in this case you can't! A sad legacy of pre-generic times

"Butt butt#get()" would be a good username if nonalphanumeric ascii was allowed.

The verbose-ness of Java's terrible broken type system is nowhere near as annoying as dealing with the lambda idiosyncracies. Being unable to throw non-runtime exceptions from most lambdas is really annoying when you run into it. It's worse when people are addicted to overusing Optional.
