Solution Overview
Problem
Current methods for visualizing complex molecules in two dimensions lack effective representation of physical properties and structural fidelity, particularly in macromolecular structural studies and drug discovery, where three-dimensional data is challenging to compress into meaningful two-dimensional visualizations.
Innovation Solution
A system and method that compress three-dimensional coordinates of complex molecules into two-dimensional graphs with minimized structural loss, using nodes and edges where each edge represents a shared physical property, and node characteristics reflect individual properties, employing a cost function to refine coordinates and preserve structural features.

Engineering Contradiction Analysis
1Ease of operation
If three-dimensional coordinates of complex molecules are compressed into two-dimensional graphs, then visualization efficiency and ease of operation are improved, but structural fidelity and measurement precision deteriorate
Solution Approach 1:
The patent applies dimensionality reduction by compressing three-dimensional molecular coordinates into two-dimensional graph representations. This allows complex molecular structures to be visualized more efficiently while preserving essential structural relationships through careful mapping of spatial coordinates to graphical nodes and edges.
Solution Approach 2:
The patent transforms molecular representation parameters from three-dimensional Cartesian coordinates to two-dimensional graph coordinates. By changing the parameter space and using optimization algorithms, the system maintains structural fidelity metrics (such as distance relationships and spatial arrangements) while achieving effective two-dimensional visualization.
2Manufacturing precision
If cost function optimization is applied to refine two-dimensional coordinates, then structural fidelity is improved, but computational complexity and device complexity increase
Solution Approach 1:
The patent implements feedback through cost function optimization, where the two-dimensional coordinates are iteratively refined based on how well they preserve three-dimensional structural relationships. The cost function provides feedback on structural fidelity metrics, and the optimization process adjusts coordinates to minimize distortion, achieving better preservation of molecular structure despite increased computational requirements.
3Loss of information
If physical properties are encoded in node characteristics and edge characteristics, then information representation is improved, but data processing complexity increases
Solution Approach 1:
The patent merges multiple types of molecular information into the graph structure by encoding physical properties (such as hydrophobicity, charge, and molecular weight) into node characteristics and edge characteristics. This integration allows comprehensive representation of molecular data in a unified two-dimensional visualization, reducing information loss while managing complexity through systematic encoding schemes.

AI summary
Systems and methods for two-dimensional visualization of a molecule, comprising the set of particles {p1,..., p N }, are provided. A set of N three-dimensional coordinates {x1,..., x N } is obtained, each xi in {x1,..., x N } describing a three-dimensional position for a corresponding particle pi in {p1,..., p N }. A cost function containing the error in a set of two-dimensional coordinates (c1,..., c N ), where each Ci in (c1,..., c N ) corresponds to a three-dimensional coordinate xi in {x1,..., x N }, is minimized until an exit condition is achieved. The minimization alters the values of (c1,..., c N ). A set of physical properties SM is obtained, each Si,j in SM representing a physical property shared by a pair of particles (pi, pj) in {p1,..., p N }. Coordinates (c1,..., c N ) are plotted as nodes of a two-dimensional graph after minimization. A plurality of edges for the graph is plotted. An edge in the plurality of edges connects a coordinate pair (ci, cj) in the graph that corresponds to a pair of particles (pi, pj) in {p1,..., p N }. A characteristic of the edge is determined by a physical property si,j in SM for the pair of particles (pi, pj).
