CF 105544M - Task scheduler

Each test case describes a very small scheduling system that receives a list of tasks. Every task has an identifier and a priority value, and the system must decide the order in which tasks are executed.

CF 105544K - Chemical Storage

We are given a tree describing a network of storage rooms. Each room is a node, and each connection is a railroad. The structure is not arbitrary: it has a strong restriction that every node lies within distance at most two from a single central path.

CF 105544J - Lead Time Estimation

We are given a production system that can be modeled as a directed acyclic graph of jobs. Each job takes a fixed amount of time to process, and moving from one job to another incurs an additional transfer time.

CF 105544I - The Pentagon Conjecture

We are given several test cases. Each test case describes an undirected simple graph, but not in the usual edge-list form. Instead, the graph is specified indirectly as a collection of triangles.

CF 105544H - Bank Deposit Challenge

We are given a fixed amount of cash and a list of bank deposit opportunities. Each opportunity requires spending a specific amount of money to participate, and in return it yields a fixed amount of interest.

CF 105544G - A Packing Problem

We are given a set of items and a set of boxes. Each box has a fixed capacity $T$. Each item has one of two possible sizes, and these sizes are very “polarized”: every item is either very small (at most $T/4$) or very large (at least $3T/4$).

CF 105544E - Slabstones Rearrangement

We are given a set of axis-aligned rectangular slabs placed inside a larger rectangular garden. Each slab has a fixed vertical position, meaning its bottom and top y-coordinates are immutable, but we are allowed to shift slabs horizontally left or right.

CF 105544A - Counterfeit Money

We are given very large decimal numbers, each representing a banknote serial number. A number is considered valid if it is divisible by 13.
