Code a simple instance generator, like the one in Pisinger's page.
The expanding core algorithm breaks when all items fit in the knapsack.
Code a method for solving the problem in pricing format (i.e., Max with negative and fractional costs). Allow the user to choose precision.
Expanding core doesn't work if negative profits are present. Check during initialization.
Code a method to solve the problem without using the Knapsack structure.
Consider including an assert or something to warn the user of a possible overflow on the determinant calculation of expanding core algorithm.
Is there a list of types/variations of knapsack problems that Knapsacks.jl addresses? For example, does the package focus on the 0-1 traditional knapsack problem, or does it also address continuous knapsack problems and other variants?
I'm not that experienced in knapsack problems, so I couldn't tell for certain from the source code.
Code a naïve heuristic Knapsack algorithm. It may help column generation algorithms when KP is the pricing.
